Hello de Suisse Super boîtier qui fonctionne très bien, l'option Bluetooth est très agréable à utiliser. Nous sommes 3 à l'utiliser et les 3 sont heureux

Sorry for my English, I ordered a box for f30 330E, I drove about 500km, and you feel that the engine is more powerful. It's not worth a remap but good results. 314hp and 490nm, but my battery was low 45%. I think we can have more NM.

Great service thanks martin

Quick and painless installation by TDI. It is early days but the car feels a lot more responsive than before. I would definitely recommend them if you're considering improving performance and efficiency (car does also seem efficient, even though it is on map 7!) .

So happy was I with the performance and fuel consumption improvements on my (now part exchanged) E class Mercedes that I opted to have my new Merc fitted with a new chip from TDI right away. The people there explain everything and show you how the tuning chips is fitted. Their advice is very impartial but with all due respect to the staff at TDI Tuning the best thing is the thing that brings me back there, the product. On my previous vehicle I took the car on a 2 hour economy drive and achieved a 57.6 mpg which was 0.1 mpg from the Mercedes claim of 57.7 mpg. After fitting the TDI Tuning chip my vehicle achieved 70.6mpg on an economy drive of 135 miles, this was a massive increase which has saved me more £££'s (in fuel) than the device cost to buy and install. Without the device I noticed a significant drop in power on normal driving and now I will not drive around without it. The claims on their website are borne out in reality and anyone having one of these fitted will notice a difference. Keep up the great work, TDI Tuning.

The TDI-Tuning box works brilliantly on my car, the staff at TDI-Tuning were really helpful as I did not know much about the boxes they do. The team guided me through exactly how it works and how to install it and I managed to install it within about half an hour. Thanks very much!

Very good l have had 2 different versions and found both to be very good on performance and fuel l keep it on setting 4

I have just had my old CRTD2 unit re-programmed, it was a painless and fast turn around. Again, it has totally transformed my car. I don't know how they get more power and more efficiency out of these things, but they truly work. Incredible. I have told so many of my friends now. Well done TDI tuning, I just love your products.

From first contact with prompt response to my enquiries regarding engine suitability, fast delivery & easy to install. Made a big difference to my vehicle. More progressive & controllable power from the engine. Very pleased & can't thank the team enough.

Excellent support and help... fab product, had three units over the years, can't recommend them enough.. These units smooth out the lag.. and give great pull throughout the rev range.. Steve.
