Hi just put the todo box on my 140bhp kuga what a difference unbelievable total change so smooth and responsive love it can’t wait to knock up to 5 it’s on 4 now like you said so so far good thank you �

Great people @ tdi very helpful and friendly 5 * Service

Super product , had it fitted to my Fiat Ducato horsebox I cannot believe the difference, transforms the drive , pulls great and better fuel economy , Anyone with a 3.5t horsebox I would recommend you get a system fitted, top banana!

Just installed the tuning box on my M140i, what a change!! Best money I have ever spent. I usually on have my car ecu mapped but this has definitely changed my mind. Big thanks

Received yesterday....still smiling like a Cheshire Cat ����

Really good product fitted to our new civic better throttle response and power delivery. Being a vehicle tech found it very easy to fit, even if you aren't of a technical background it is still very easy. Looking forward to using the car more often.

Mercedes S500 4.7 litre V8 Biturbo(W222). I’M LOVING THIS!! After driving some 50-60 miles from installing my tdi piggyback, I cranked it up to the highest setting at 7 and boy does it feel like a freight train. No check lights whatsoever, power delivery is very smooth, installation was quick and easy. In all honesty I’m so glad I purschased this product. Thank you. Most of all I have to thank Kevin as he was not just quick to reply to my emails but also explained to me everything I asked in detail, he really cleared all the doubts I had. Excellent service really.

Big thanks to the team at TDI. Very helpful bunch of people work there. The difference can be felt straight away! The engine delivers the power ( a lot more than before) in more linear ways than ever! Keep the good work guys

So far so good on my Transit, defo helped with torque, 6th gear @30mph using less fuel, and bit more grunt for when you need to get shifting

Had a box fitted yesterday in my Ranger! Instant difference in power and feel! Highly recommend!!

After having a performance remap carried out on my old car then then soon realising I wish I had gone for an economy map due to fuel consumption I was on the hunt for a tuning box that I could vary the map. I came across TDI-Tuning, after doing lots of reaserch via forums to see people experiences with the box I bit the bullet and purchased one. When it arrived I immediately went out to fit it, was such an easy install, little bit tricky getting to the map sensor in my A6 but still doable without removing anything. Once fitted I could immediately feel the difference, car felt more responsive and pulled better through the gears. Putting the box into eco mode really showed the MPG increase when doing motoway runs. Highly recommend

TDI boxed our M4 earlier this year, and we were delighted with the results. Take a look on their Facebook page to see the pics. We decided to box our X6M50d, and wow, I mean wow. It's fekking awesome, and now gives our M4 a good run. Totally nice team, great service, and superb results too. My advice, go for it :):):)

Well I decided to take my 3.0L Jaguar XJL in for a TDI Box. The box is simply brilliant and does exactly what it says on the tin. A 500mile motorway round trip gave me a total average of 54mpg, which is about a 10mpg improvement. Enough said Not to mention the service was outstanding.

Just fitted box to my jaguar F pace 3.0D s ! What a difference , so easy to fit as well ,

Had mine fitted to my Focus st absolutely made up with how drivable it's made the car .. the extra bhp is a bonus too Top product buy with confidence

Very easy to deal with, polite, helpful doesn't quite say it, we had a tuning box on our 1.6 TDi VW polo SEL and when we got our Scirocco we took the tuning box off and had it redone by TDi tuning to fit on the scirocco, the car has never been better, the box is adjustable too, it's very easy to do, I don't think you could get this sort of upgrade cheaper, don't take my word for it try them. Their service is second to none.

DPD messed up the delivery but superb end result ! Good job TDI Tuning!
