i have used TDI for a few of my cars and they have all worked well much more power-torque , last one was an exchange for a different car quick turnaround and reasonable cost too . easy to install and the picture of the engine helps a lot Good product reasonable prices

Cannot recommend enough I cannot thank the team enough at TDI Tuning for their first class customer service, I’ve been immensely impressed by the product too, the performance gains are great and the system was easy to install myself. This is my second system and I’ll definitely be back for my third when I get my next car Thanks again!!

Service was good, price great, the tuning box (on an Audi A4 2.0TFSI) certainly seems to have woken the car up a bit. Also if the trip computer is to be believed fuel economy has risen an easy 10-15%. Only problems I had was that the fitting instructions were for a generic VAG 2.0 engine rather than specific to my car so none of the connectors were where the instructions said they would be in the engine bay so had to have a little root around for them and then the cable ties that came with the kit were not long enough to mount the box to anything suitable so had to use a couple of my own big ones.

Pleased with performance and the MPG is noticable too. Would buy again!

Great service from a online Representative named 'Lewis' i think? Quick next day delivery, fitted myself in 5 minutes with the well written instructions. My F30 220D now has that extra bit of kick that it was missing.

Brilliant product with a lot of money savings over the years

For more car power, and mpg, this company's tuning boxes work wonders!

Great product good team. Much healthier option for my Merc C Class 220d 2016 car then remapping and amazing performance output! I've always remapped until I drove past the TDI tuning shop and decided to give it a go as i tried a few remaps and they caused problems with my car. Every car I own will be going there now! Raj

Found TDI to be very helpful with making sure I had the correct version as my layout not shown initially. Have installed it, very simple seems to give more power but not used enough to comment on fuel use as it is on motorhome so only gets occasional use.

Really good, retuned my old Box for my new car at a great price. Goes like a bomb, Highly recommended.

Had mine fitted a few months now, fitted to a 2017 Ford Ranger 3.2 Auto. Completely transforms the truck and it’s certainly more nimble. With the added benefit of the Bluetooth option changing modes is so simple and no bonnet limiting. Faultless and a happy customer, highly recommended.

So far so good. The box has certainly made a difference to the way the car drives, it is smoother and pulls better through the gears. The extra torque is noticeable especially when under load, such as overtaking uphill. I haven't played with the different settings, just left it on the factory shipped setting, but may see what difference the higher settings make. Overall very happy with the tuning box.
