"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 "

"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."

"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. "

"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
