TDI Tuning Reviews 1,545

Great product and easy to buy and install.All this greatness let down by the company nominated to deliver,saying I wasn't in when I had been in waiting.Turned out the driver didn't try to deliver due to road works in the area.

great price - great product - great customer service. Very happy with the power gains

Great online and email comms, simple install for Audi B8 S4 - two plugs and off you go. Bluetooth is excellent, can use the buttons I guess once set, but nice to adjust from 1-7 on the go to see the impacts. Delivered prompt, and have recommended and friend has bought and installed - nice product

First class as usual, always helpful, prompt, no messing about. Love it!

Blew a 72k diesel (over serviced) motor 2 months after installing the tuner, to be honest I don’t know if it was the tuner but the timing doesn’t look good….

Bought a few items from this company over the years and no complaints. Easy to get on the phone or mail and respond quickly.
Blutooth app linked to their tuning box is a gamechanger, so simple straighforward and most of all reliable. MPG increased approx. 4-5 since fitting which is impressive considering the performance. Boost seems to surge occasionally on certain settings but it's all fun and wheel spin !

Overwhelmed with difference in car

Found exactly what I wanted easy order process and fast delivery

Talking directly to you on the phone about the product answering all my questions directly

easy to change chip box over to another vehicle, first class servise,from day one

I struggled to install the kit myself, so I messaged TDI and they were amazing - and offered to do it FoC if I could get to Chelmsford. Not saying they'll do this for everyone though!

Excellent power output and vastly improved mpg now; really worth the drive to Chelmsford AND the money I spent on the tuning kit.

Thanks again to all involved.

Don’t waste your money on this garbage product !!. I payed around £350 for a tuning box with bluetooth for audi s3 it felt a little quicker but not much . I decided to put it on a rolling road costing £200 and was shocked by the results . Torque had actually dropped 1 nm from stock and bhp had gained by 23 , nowhere near the 70 advertised .
Sent many emails upshot is no refund they just don’t care it’s false advertising will be reporting to trading standards . They actually tried to tell me audi had underpowered the car until i got a second rolling road before a PROPER remap which gave me brilliant results .

Awesome experience as per, bought a reprogram and they were swift at sending out a new harness and the flash. Feel the difference on my new car already 👌🏻👌🏻 Only thing is delivery, parcel force are rubbish 🤣

When I was debating on buying a TDI tuning box oppose from a stage 1 remap I did a lot of research in to pros and cons of both. Value for money with the numbers quoted from TDI tuning made it a no brainer. Engine safe and vigorously tested. I took the plunge and bought it for my Cupra 300 ST. Maybe I was expecting too much? Easily fitted and off I went testing out the different modes. It’s fair to say I’m a little disappointed as I thought there would be a big noticeable improvement. I just couldn’t really feel a massive difference. I’m a bit let down but at the end of the day now I know. Probably a bit of a waste of £300 that I could have put towards a stage 1 remap. Don’t get me wrong TDI tunings concept is good but just not for me or what I expected :( if I could give 2.5 stars I would as I want to be fair but it’s just how I feel.
