"Mr Docherty was a happy DPT user having a unit on his Jaguar X Type 2.2. He upgraded his vehicle to a new Jaguar X Type 2.0 and enquired if he needed to have the unit reprogrammed & what charges were involved. We check and assured him the unit could be transferred withour any changes and thus no additional costs. Mr Docherty emailed to advise ; Thanks for the info re swapping the module onto my 2.0 x type from my 2.2. I didn't do the original install but I simply reversed the uninstall I did myself and it is working like a dream, I was really surprised that the module makes such a difference to a brand new car straight out the box!!!!"

"Mr Burman an existing & happy DPT user recently approached us as the the Vehicle Manufacturer of his latest car had advised that fitment of DPT would automatically invalidate his warranty. We contacted the manufacturer in question to advise that they were potentially in breach of European Legisllation and asked them to check their stance re DPT and vehicle warranty. After investigation they replied as follows; you are fine to fit the DPT box to your car, it will only invalidate your warranty should there be a direct engine failure due to the DPT unit - Martin told me this has never happened and they have a £2 million insurance scheme in place if it should. Glad we have sorted this out and sorry for the misunderstanding on our behalf, I hope you can understand from our point of view we need to protect ourselves should a warranty claim arise and it turns out that we said you could fit the DPT unit without it effecting your warranty. Mr Burman ws extremely happy stating; I will hang on to the e-mails during the warranty / servicing period for my new car in case the situation arises again. I will also continue to expound the virtues of DPT units to all and sundry, with the added proviso that the after sales support is second to none. It is highly unlikely, but I hope I might get the opportunity to meet you at some point to thank you personally. Who knows, one day DPT units could be as common as Corn Flakes! My original e-mail stated I was glum and needed cheering up, and you have cheered me up no end, I'm really happy now. Thank you very much indeed."
Mr Ray Burman - Surrey
"I have recently purchased one of your units and I am very impressed with it. I was wondering if you did badges or stickers of your logo as I would love to promote the product on my car........................... We do not have any such logos - stickers available. It is something I will bear in mind for the future. He replied .................. I am very very pleased with it, the extra power is a bonus and the added mpg isoutstanding, which is why I wanted to remove my TDCi badge and put a DPT one on there. Ah well, keep me informed if any developments come about from this."
Mr Neil Thomas
"I have had a chance to try the car with the caravan on the back and the difference is amazing, on the long hills on the M1 around Loughborough the car use to slow down and change down but now it goes straight up the hills in top and does not slow down. Mpg is up all-round by about 4 to 7 mpg depending on use and the engine is quieter and smoother. Money well spent."

"Citroen C3 1.6 90BHP - Many thanks for an excellent product and thanks to Mark Chambers for his assistance and courtesy. Most impressed."
Ronnie from Lincoln
"I would just like to confirm how pleased I am with the DPT unit you have fitted to my Range Rover Vogue. The unit has been fitted for a few months now and has had the effect of making the engine smoother with noticeably more torque. Also the fuel consumption is now averaging just under 28 mpg whereas before it was typically 23.5 - 24 mpg. With my annual mileage, this means that the unit pays for itself in about 5 months. Many thanks for you help. "

"Mark, it is three weeks since you fitted the tuning unit to my Mercedes Benz CLK CD220i and what a difference! Acceleration is much improved both from a standing start and during normal driving. The car is an automatic and when kickdown is used it flies. For the first 1000 or so miles since I bought the car the computer gave an overall MPG reading of 41.5 mpg. Since I had the unit fitted I have covered another 600 miles with an average of 44.7mpg. On a recent return journey to Windsor of 300 miles I saw 49.5mpg. I reckon that I should now average around 44-45mpg whilst using the extra power. I would like to thank you Mark, for the friendly and professional way you went about fitting the unit and your follow up call to see if all was OK. I will definitely recommend both you and the unit. "

"I have recently had one of your units fitted to my 2003 Audi A3 Sport Quattro 1.9 TDi PD, and I would like to congratulate you on my findings. I am yet to discover the full benefits of the unit as I have only had it for a day, but I have seen a decrease in fuel consumption on my frequent journey. I am also very pleased with the performance; gear change is smoother and less frequent, and all together has transformed the driving experience of my Audi from very good to outstanding. I can't help but have a beaming smile from ear to ear every time I turn the key. I would like to thank you and Car Care Services (Mark Tranter) for excellent service and advice and of course the transformation of my vehicle. Earlier this year I sold my MK 5 VW Golf 2.0 TDi (140bhp) because I got very frustrated with the flat spots I experienced during the rev range and bought the Audi because it drove better. I am glad I did buy my Audi but if only I had known about your Company then....... "
Matthew, Kidderminster
"Although fitting to my peugeot 306 HDI was a little awkward due to the location of the CR sensor the whole process was simple. Immediate results! I had considered a remap but the tuning box is so much less invasive and works excellently. I would highly recommend the DPT as it is one of the few boxes that offers switching between different modes for various driving styles as well as the excellent warranty. "
Owen Arman
"'I run a Hyundai Tucson. Its the 140 bhp version, but still it lacks a bit of power and its a heavy 4x4. The tuning box has made the car smoother, the gearing a lot better and it pulls faster and harder. I have the performance setting on it as I have a caravan also. I've not towed with the tuning box yet. Even with the performance setting I am seeing a consistant improvement in mpg. On a measured / frequently covered journey of Derby to Bristol I was previously getting an average of 38 mpg I'm now getting about 43 mpg - so a 13% or so improvement and that is with driving a bit fast and harder. Round town were previously the car was getting quite poor mpg (didn't really measure it, but it drank diesel) I am seeing round the 30 mpg mark. Its also easier to drive in town due to the extra power and therefore less gear changes. So all in all a good investment that will pay for itself quite quickly."
Andy, Midlands
"Saab 9-3 1.9 Tid - 150 BHP Just an update of how i am finding my DPT. On the way up to having the unit fitted, i was averaging 54mpg. On the return journey i averaged 68mpg (I even saw it go upto 78.4mpg at one point). I have noticed that the car ticks over better, is also smoother running and it doesnt have as much engine breaking either. My journey to work i usually see about 42.5mpg to 44mpg, however last night it went to 54mpg. Overall, i am very pleased and have already told a few people about it. "
Serving Traffic Police Officer
"Hi Tony Thanks for fitting the DPT box at short notice yesterday. pleased to report that target 50mpg has already been achieved! Must have been that following wind. Increase on one run (combination of A roads and urban) of 20% (42.5 to 51mpg). shall send a full report in 2 weeks. Follow up ............. Just a quick update on the DPT tuning box you fitted to my mercedes 220CDi a couple of weeks ago. The fuel economy continues to amaze - so long as i dont use to much right foot. on a like for like basis i am getting nearly 10 miles more per gallon or 20% improvement - great news if you do a lot of miles! the engine also feels more responsive and better to drive is an additional bonus. Happy to recommend to any of your other customers and friends etc. "

"The following e-mail was sent to Tony Gibbons of Motorworld in Wantage. It speaks volumes both for DPT and the quality of service and workmanship from Tony and his team; I just wanted to write a quick email to you to say how impressed I am with the DPT unit which I had fitted from you , I have seen average gains of over 10 m.p.g since fitting to my BMW 520d , the power is noticeably up , and the delivery much smoother as well. I also wanted to say that the service and advice I got from you was first class such a great pleasure to meet you I would be happy to keep you informed on figures,keep up the good work."
Mr Simon Douglas, Oxon
"You answered my questions in an earlier email. I had already read the article by Iain Robertson which you attached and so pursued the same path as the journalist had done and contacted Mark Chambers. He was more than accommodating and installed it on a Sunday at MY convenience. His attitude and attention to detail are to be credited as was his information and knowledge of the unit he was installing onto my Skoda VRS. I literally came away filled with confidence and was not disappointed. My car had covered only 7k when the DPT was added. If anything the engine ticks over more smoothly and responds faster to throttle with the hike in BHP & Torque. Coupled with the added value of fuel economy when driven sensibly, I am a very very satisfied & happy customer. Anyone who runs a diesel powered vehicle should not hesitate investing in one. My car is still in its running in period and it feels & runs absolutely great. My completed Warranty form is in the post on its way to you. Thank you very much indeed for your back up which again only adds to my confidence."
Graeme Mumby, Lincolnshire
"I could never have imagined the increased performance your unit has given my Audi A5 3.0tdi Quattro. It absolutely flys!!! And I’m returning at least 15% on fuel economy. A superb product that really works!! "
Ash McKee, Telford
"I thought you might like some feed back as to how the installation of the tuning box went with CC Motors in Sheffield yesterday. Well, it was a very nice experience. Chris Cowthore was extremely pleasant. The attention to details in the way he fitted the unit was just first class. All the cables were very carefully routed and tied back, then checked and rechecked to ensure they didn't chafe against the bodywork, the fuse was nicely positioned so I can get to it easily, excess lengths of wires were trimmed and terminated properly. He even added spade connectors to the battery for ease of disconnection/reconnection in the future. I have not seen anyone who takes so much pride in doing a good job since I last saw a master mechanic aligning a main engine to a gearbox of a police launch over 20 years ago! He then took his time and explained to me how the whole system is connected up etc. I simply cannot fault a single thing. What could have been a 10 min job took the best part of 1/2 hour to make sure it was "just so". It is very reassuring to know that there are still people like Chris around. "
James Wong, Operations Director, CAN Structures Ltd
"I tootled off to Mark Chambers Sunday 6th and had a unit installed. Excellent service and I'm delighted with the product, the results being instantly recognisable. When I get used to the extra power I'll benefit from the economy factor. Thanks once again "
Graeme Mumby , Lincolnshire
"More news on the DPT economy module I told you about last week. I've now had one fitted to my oil-burning Range Rover and early indications suggest that economy has improved from 23.4mpg to 29.8mpg. If I drive like Sister Wendy, I can get the trip to nudge over 30. Given the remarkable results I've had on my Jag as well, it looks like this £300 black box will pay for itself in less than a year at today's derv prices. As far as I'm concerned, It is the only diesel economy device that really works. "
Quentin Willson - Motoring Journalist & Presenter
"Just a note to say thank how pleased we are with the installation program you have put in place for our DPT units. As you know the 160 units we have ordered are for our VW T5 based minibuses spread all over the UK, which only return to HQ periodically. Your flexibility in carrying out the installations is much appreciated."
Richard Baxter, Transport Manager Titan Travel
"Just wanted to say thanks, received the unit today that I ordered on Thursday, I‘ve only owned the car for a few days and it’s the first diesel I’ve owned so I was missing the rev range a bit, WOW not anymore! I can’t believe what a massive difference it’s made. It has completely change the driving experience, no more turbo lag and it now revs! "
Mark Ridley, Hertfordshire
"Just to let you know how pleased I am with the DPT unit. It really has transformed the car, much more than I thought it would, no flat spots, always has power, no need to use kick-down. Thanks very much for a Brilliant Job. I must say the difference in performance is outstanding. It now feels more responsive and far less sluggish than before. I haven’t had the opportunity to test it out whilst towing the caravan but anticipate much better pulling power. I would recommend this unit to anyone who drives a Discovery TD5 diesel vehicle as the difference is truly amazing. Hope to see you all at the Caravan Show at NEC next week. Would also like to thanks BR Special Tuning for the fitting the unit very helpfull and a must for fitting the unit in my area. www.brspecialtuning.co.uk "
Dave . Herefordshire & Worcestershire
"Hi , I bought the unit at Autosport 2008 earlier this Month. Thanks for persuading me. It's amazing. My car [Alfa 159 2.4JTD] was great before i fitted this but now it is like having a new engine in there. Also it is using less fuel too. Why everybody does not have one of these I don't know. Keep spreading the word, i certainly will."
Graham, Cumbria
"Just to let you know the result of fitting the power box to my camper van at the N.E.C. on 20/10/07. My van is a 2007 4.5 ton Burstner T821 tag axle van with the new Renault 2.5 150hp engine. From new I have had a lag in power when exiting a corner or roundabout until the revs rise, this is why I gambled on the DPT box. Since fitting, the problem has totally disappeared, and the power increase is exceptional, beyond expectations. Also, diesel consumption has gone from the best previous of 25.7 mpg to a present 28.9, which for a big van is astronomical. Being a new engine to you, you anticipated that the horsepower would go up to 184 from the factory 150, could you let me have official figures so that I can advise other campers for you. Thanks again, your sales spiel was well founded."
John Adrian, West Midlands.
"The DPT unit finally arrived this afternoon; I must say the difference in performance is outstanding. It now feels more responsive and far less sluggish than before. I haven’t had the opportunity to test it out whilst towing the caravan but anticipate much better handling. I would recommend this unit to anyone who drives a diesel vehicle as the difference is truly amazing. "
David Parnell, bought at the NEC Caravan Show
"The DPT device is working faultlessly in my car, producing 211bhp or thereabouts, with around 300lbs ft of torque from 1450-3900rpm. Its fuel economy has improved dramatically to exceed the Official Combined figure of 49.6mpg. In fact, it is currently returning 51.3mpg average, a phenomenal result, in normal daily operation. The acceleration has improved, dropping the 0-60mph blast down to a petrol equalling 6.8 seconds, while the top speed (confirmed by the GPS smart-nav device fitted to my car) is a genuine 161mph. So, has it improved? You had better bloody believe it! And I have been writing as much. "
Iain Robertson - Motoring Journalist (Skoda Octavia vRS)
"The following enquiry was received via our website ............ Had used a previous tuning unit on my new vehicle and have had problems ever since. Engine managment light keeps coming on and also have had huge power losses. So Mecrcedes have had to reprogram the entire system and so have thrown the tunit system in the bin. I'm therefore wanting to replace it with your chip, but need some help and advice on wether or not i'll experience these problems again.......................... We assured him our unit would not cause the problem and he had one fitted. When asked for feedback he replied .................. Hi, I've had the DPT fitted by J & J Campsie garage in Biggar. They fitted it in no time at all, which puts the previous installers to shame really as they took over an hour. Was also very happy with the service, it was clear from the start that they knew what they were doing. The van's running so much smoother, big difference in torque and performance. The jump to 520 from 440 in torque makes all the difference. In fact its even giving a better mpg on the perfromance setting, so am really pleased so far with your product. So impressed am actual saving up now to get one fitted to my audi. "
Darren Corbin, Mercedes Vito operator
"Just to tell everyone, I had one of these fitted to one of my Mercedes Vito's in July. I have since had them fitted to the other 12 we own. What a great product, I can not believe the difference in power and the fuel savings will make payback very quick. Well done DPT. I'll recommend you."
Mr A J D Crawley
"Just a note to say thank you. Had the unit fitted about 5 weeks ago, just back from 3 weeks touring with my van at the back as ever. I almost forgot it was there, what a fantastic bit of kit. I thought my BMW 330D was powerful before i had this fitted. But have to admit the difference was worth every penny. The guy who installed it was a great help and set the box up specially for me, NO ectra charge at all. Well done keep it up guys, you deserve the positive things everybody is saying about you."
Graeme P. W. Midlands
"The following was an e-mail received by a user who'se local dealer had allowed him a DPT on trial for a week..... Just to let you know I've just got back from touring the lakes. I wont be having the DPT removed as it feels like I've had a bigger engine fitted. Great Product would recommend it to anyone. "
Alan Barker, Northumberland
"I had your system fitted to my 5 year old Citroen Picasso two weeks ago. In that time I have purchased 1345 litres ( 29.6 gallons) of diesel and covered 1628 miles on mixed roads and not consciously driving for economy. This works out at 55 mpg. The difference in acceleration particularly in 4th and 5th gear is very noticeable. In short I'm very pleased with the system and have mentioned this to the garage that fitted it, Gordon Motors of Wick, Caithness. "
Ernest Jones, Highlands
"I just wanted to say that i'm back from a week away in Yorkshire. The first time we had towed our van since we had the unit fitted. In fact the caravan is why we bought your unit. It was exactly as you said plenty of pull when my car would normally be slowing down. No frustration of having queues building up behind us. Great Thanks. I'm off again in 2 week and will be recommending this to everyone on site as i did last week."
Gerry & Gillian, N Ireland
"I've had other units on previous cars and they have been OK. I had the DPT one put on my current car a 1 y.o. Jag. It has been on about 6 weeks now and its great. Well worth the price and i managed to fit this one myself, not bad for an accoutant! I'm saving about 11% on fuel too which seems amazing for a faster car."
Andrew, W Midlands
"I have had this unit on my 6 month old BMW 320D for about a month now. I had no interest in the added power but was assured it would improve drivability and my fuel consumption. (i do a lot of mileage). I must say the car drives like it should have when i first bought it. Excellent, Thank you."
Gordon, Highlands
"We used the unit on our Renault Espace which we use to tow our Bailey caravan. First trip with the unit last weekend was a dream, your installer set it up so i would get the most benefit when towing, the change is great. The extra pulling power makes a massive difference and the fuel saving will make this little thing pay for itself this season. I would not be without it now and i am no longer thinking of buying a more powerful towing car either so you really have saved me money, thanks."
Roger, Carlisle
"I bought the DPT after seeing your van out and about and had your installer fit it to my business van (Mercedes Vito). Its a great product, I carry a full load without struggling to accelerate or get up inclines, I even take the van at weekends sometimes as its a great ride."
Alan, Newcastle
"I regularly tow cars to track weekends and although i bought the DPT to give me better on road performance i am really pleased with the extra power i have when towing, i no longer need to drop gears to get up hills and will certainly be recommending the unit to the guys at the track, oh and i am saving fuel too , Thank you."
Sammy, Leicester
"Just want to say thanks for the DPT . I managed to fit it to my Mercedes CLS 320 CDi all by myself using the instructions provided, i knew it was possible to improve the output of a diesel engine but i am very surprised how much extra i could get out of what was already an amazing car."
Shaun, Sheffield
"Just got back to London. Extra performance in the car is fabulous, especially with instant acceleration. But economy ........ Where do I start?! My average mpg from London to Leeds prior to having the box fitted on the 3 litre engine was between 28mpg and 30mpg. My best was 32.7mpg driving very economically. I have just got back home and the readout displayed 38.1mpg. Fabulous and thank you, fitted in under 10 mins by your installer and immediate results, amazing."
Garry, London
