Good quality products and support.
Good quality products and support.
Used a couple of their pedal boxes on a
VW Golf GTD and a couple of Skoda Octavia vRS diesels over the years.
Work well in sorting the accelerator pedal response to suit my driving.
Found Andrew at DTUK very helpful if you want any advice on their products before buying.

Long term test, purchased back in 2023 to fit to my 335d. I average around 25k miles per year, at first it was good and added a good amount of torque mid range however after 6months was starting to for the car to limp mode and take away all boost, (kind of dangerous when it does this mid overtake) lowered settings to mitigate this and would then run well for another 6 months before happening again. After 2 years of this occuring, i ended up only a little over stock and still had issues. Have now removed from vehicle completly and everything seems ok.
Pedal box pro
Great company to deal with, very helpful in emails about the product. Ordered the pedal box pro arrived next day. What a difference it has made and so much fun it really compliments my stage 1 remap. Very easy to install with clear instructions. Many thanks
Mercedes AMG gearbox tune box
I bought the gearbox tune box for a 2018 E63. The difference it has made to shifting is very noticeable and of course improved. Especially at comfort mode where AMGs tend to be a bit jerky at shifting. It is a pricey mod but definitely worth it if you are a car enthusiast.
Harness quality is subpar
Crap harness falls apart and causes none stop issues, the unit and software are great and it's great when it's working
SQ5 pedal box
SQ5 pedal box
What a difference the pedal box makes ! Got it today and installed so only had chance for a short test drive but wow what an instant improvement.
Drives like it should have been when coming off the production line.
Added bonus of the immobiliser just the icing on the cake !
Ordered and delivered within 24 hours and literally 15 minutes to fit but only because the trim made it tricky otherwise be 2 mins to fit !
Buy with confidence.
Top Notch Highly Recommend !!!!
So checked out many of the tuning box suppliers and looked at their histories and backgrounds.
I chose Dtuk as they appeared to be the market leader. I spoke with Andrew via email and he was very responsive and helpful and overall my experience was excellent. Once my order was submitted my tuning box was dispatched and i recieved it the nextday.
Installation was quick and easy using the guide that is specific for my engine and i can confirm that although I have had the box fitted for 2 days and have only had on the dynamic setting that it has had a big difference to how the car pulls and on top of that I can see my fuel consumption has improved already albeit it will take some more time to confirm this overall.
All in all on first impressions I highly recommend Dtuk if you are in the market for a tuning box 👍🏻👍🏻👍🏻
Peddal box pro.... BRILLIANT
I purchased a peddal box pro for my 2009 Passat R36 a couple of days ago, I was contacted by Andrew just to confirm the connection plug/pin, very professional and knowledgeable and helpful, I broke the connecter when checking but Andrew reassured me and once he confirmed which connector my car required the item was processed it was sent out NDD Royal mail.
The product to install took all but 5 mins. Very easy to install and get set up even the app is very handy. I xould feel an instant difference in the way the car responded to the pre set programme also there's ways of fine tuning way you use the accelelerator pedal. For me the sport and sport plus options are perfect due to my driving style, but anyone with a dsg box knows how laggy they are but not anymore, this thing is very effective at getting rid of that lag and it's instant at responding to your toes let alone the foot pressing on the peddal. Also you got the benefit of the added immobiliser for the accelerator pedal which is a brilliant feature, once activated and the phone and fob have powered down or disconnected from the transponder, you switch off the vehicle exit and when you switch the vehicle back on, until you don't press any button on the fob to activate it or the phone's bluetooth connects to the vehicle again the accelerator peddal won't respond to you smashing your foot to the floor. Reccomend the product especially to the VAG vehicle owners who relate to the lag I'm talking about, I'm sure it's not just the VAG cars with DSG box [brilliant gearbox] that have the lag from sending the message that you have pressed on the peddal. DON'T MISTAKE ME THIS IS NOT A REMAP OF THE GEARBOX BUT JUST A MESSENGER THST TELLS THE ECU THAT YOU HAVE PRESSED THE ACCELERATOR PEDAL MORE THAN YOU HAVE AND IN TURN REMOVE THE LAG. Please feel free to correct me.
For me it's a NO BRAINER. Just need to get a ECU and TCU map.

Bought a dtuk remap for my 2023 t roc r. They Rang me to confirm engine spec as coupe of choices for car. Very professional service and polite service. This is the second time Iv used them. I bought a box for a q5 5 years ago. Never had any issues with these guys.
My troc r also has a very noticeable power increase. These guys and gals are awesome
Great Comms and Fast Shipment
I purchased a PedalBox Pro for my 370z Nismo. I was contacted to provide more information about the connectors, all comms were professional, and helpful. Surprisingly the box arrived a couple of days later for the Nismo. Having installed it today. Well firstly its straight forward and I am no mechanic. Secondly the app and the remote work well. Firstly, wow what a difference to the throttle response. Being the Pro Moel I am able to lose all the cables and everything connect via Bluetooth. A really easy Mod which gives a real improvement to the throttle lag. A worthwhile investment. Great support, worked out of the box and plug and play. Very happy. This is how the car should have been out of the factory.

Bought a Pedalbox for my 2020 VW Tiguan SEL 2.0 tdi

DTUK were quick to respond to emails

27.12. Mis fitment was due to your poor quality pictures.
As for full refund, i wasnt asking for that, i was asking you to help me?
But seemed the helped stopped as soon as i recontacted you.
That box has only been used on two cars mini and merc. I have owned prior boxes for golf and tiguan.
But I will leave this in your hands, seen as you reckon you pride yourself on looking after customers.
AVOID AVOID
I used to be a dedicated buyer for over 7yrs, but since the recent treatment from them regarding the upgraded loom i purchased for my brand new TRoc, and the attitude that came with it. Has put me off them for good.
Fobing me off saying it was my fault that box wouldnt turn light up etc. Due to there poor quality instruction manual and not being up to date with the MY24 T Roc 2.0 R Line 4motion 190.
There are better suppliers out there now.
AVOID.

Just purchased a box for my Hilux
Just purchased a box for my Hilux.
Huge difference to my truck, performance hugely improved as is fuel economy, also easy to fit.
I had a small problem due to my own ignorance but one of the guys from DTUK was emailing me and texting me on a holiday Monday at 7pm doing his best to help me.
Turned out to be a loose earth on my battery.
Fantastic service , cant recommend enough.

Tuning box/pedal box
Recently bought tuning box from dtuk, really good, did struggle with one of the plugs ( Audi A1 1.5tfsi 2023 ) but wow does it work. Also just decided on the pedal box ( simple install ) GAME CHANGER. What a difference. I think my car is now actually faster than my previous A1 competition 2.0 2020 ( acceleration, don’t know about top end ). Everyone I contacted at dtuk with any queries replied almost instantly. Fantastic customer support. Can’t recommend these guys/girls enough.

Great service from Andrew at DTUK I have a pedal and tuning box and wouldn't be without them 👍🏼
Outstanding Customer Support
I researched a range of manufacturers before buying a tune box. What became clear very quickly was the excellent service that people described with DTUK. I have to say that this is by far the best company I have ever dealt with for customer service and technical support. They really are head and shoulders above the rest. Amazing products backed up by amazing support. Many thanks to the team at DTUK for educating me and helping me.
A pleasure to deal with
Third time i’ve used their products and have always been very pleased with the results and the support. This time I acquired a 2nd hand box privately and DTUK re flashed it for my car as well as the accelerator peddle. Would definitely recomment
