Visited the guys in Manchester this afternoon. Great service thanks again.

great service. great product. Thanks guys

Ordered a box for my Mercedes E250 CDI night edition. Fitted this myself, took about 25 minutes. Difference is night and day in performance, throttle response and no turbo Lag at all. Fuel economy has increased by 5-10% and performance by 25% roughly. Highly recommend it and well worth it.

Finally got the box installed on my 208 GT line with the help from a local garage, holy god what a difference its made, no flat spots acceleration is incredible, took it on a run and was returning MPG figures of 88.5mpg, simply worth every penny

Purchased a tuning chip with Bluetooth connection for my SQ5 other week had chance to fit it today with simple instructions I spoke today with Stuart a helpful chap from TDI Tuning it seemed I had trouble with the installation only due to my own fault I hadn’t ensured one of the connections wasn’t fully connected, it was good to have someone only a phone call away to guide me in the right direction , I have noticed a difference and very happy with the results , I did fit the chip my self they do send you simple steps to complete il I will advise if you was to go down the same route as me is to ensure all connections are firmly in place and to follow instructions given carefully .

Received my tuning box within 48hrs. super fast service. only took me 5 minutes to fit and most of that was securing and routing the cables. The user guide was excellent and very well laid out in plain language so anyone can follow it. I've only done a very short run out with it fitted but the difference is noticeably better at low speeds. can't wait to open her up properly on a faster run and see what it can do.

After purchasing a BMW 435d with Autovogue styling and performance upgrades, I had an issue with a drivetrain malfunction message. I took the car to my local garage who diagnosed the fault with all issues pointing towards the TDI tuning box and removed the box. On finding this information I went back to the dealer where I purchased the car and also Autovogue directly, neither were interested in resolving the issue. I called TDI and spoke with Stuart Hill who couldn’t help me enough. He emailed me with their address and asked me to post the box to them. I did this and within 2 days got a call saying he had reflashed the box with the most up to date software and he was posting back with fresh installation/fitting instructions. This was all free of charge. What a fantastic service. Stuart, you made this real easy. When the other 2 parties showed no interest, you made TDI Tuning accountable for rectifying the issue. Much appreciated.

Very friendly service! Used them when I had my Freelander and made a big difference to my fuel economy! Highly recommended

Had a few issues getting it installed myself thanks to BMW shoehorning a big engine into a small car. After calling them up, booked it in the following weekend and had it fitted properly for free. Excellent service and very friendly staff... my M2 Comp now has me giggling uncontrollably every time I put my foot down. Could not recommend enough!

Just bought a tuning box for my Ford Kuga TDCI after hearing great things. Really impressed by the improved power delivery and I’m seeing 4 miles per gallon extra too. I spoke to Dom on the phone which was very helpful and answered my questions in detail. I wouldn’t hesitate in recommending these guys to anyone looking for that extra power.

Best tuning solution around for me, easy to fit and really makes a difference. Fast delivery too." Cheers Guys

Great service great product
