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.

I ordered a box from them towards the end of 2024. Worked perfectly fine for quite a few months and was happy. After a while it stopped working. Contacted them but would only send a new part out which I no longer wanted as worried for any damage to the car. They don’t refund passed 30 days so just be aware.

Have contacted technical dept multiple times speaking to Jake, now getting no response.

I have 3 vehicles with TDI Tuning Boxes installed. I also like to take the advantage of the fact that these can very easily be moved into sometimes very different vehicles any time once the correct loom and revised tune has been purchased. For example my Mercedes ML320CDI box is now on my BMW 328i with only a revised bluetooth tune download over the internet and the relevant loom purchased. The turnaround time these guys provide is incredible - purchased and delivered by DHL to me here in Australia within 4 days! The communication and support available from the team when I have any questions is of a standard I rarely experience anywhere, never mind in the automotive industry. Keep up the good work guys!

Absolutely first class service great tech support over the phone unfortunately I had to return my unit as I was unable to fit due to a problem with my car they refunded the full amount the day they received it back would definitely recommend and hope to use them again in the future

Fantastic service from pre-sale to after sale. Tuning box has improved MPG and torque, which is great for towing my caravan. 5 stars all the way

So after waiting, waiting and waiting for over 3 years for the Bosch ECU to be cracked on my VW Transporter for remapping I gave up and took the plunge to purchase the appropriate chip for my vehicle. After some back and forth emails to make sure I was completing the install correctly mission success. First test run completed to Skeg Vegas and the improvements were very noticeable in torque and smooth acceleration. Thanks to the team for all your support and patience.

Iv ford focus mk4 2.0 diesel 150 now 195 what a difference it makes love it working perfect. 6 months now

When I tried twice to install it I failed
I wrote to you asking for help and was told there was no refunds
The best you could do was reprogram the unit for a different vehicle
I have now paid a garage to install it and guess what it didn’t work
Complete waste of money

Hi I've just bought TDI tuning box for my BMW m135i no issues runs amazingly so much power especially in setting 7 what the crazy thing is the fuel economy has improved massively especially in mold 4 was easy to install and the pictures were very clear customer services excellent thank you TDI tuning.

Excellent piece of kit, wiring up was relatively easy, although you will need to be mechanically minded to do this yourself, I had it wired up in 20 mins with no issues, instructions are clear with lots of photos for reference. You can have TDI wire up for you if you can’t understand the diagrams.

Drove around on map 4 for around 30 miles to allow the ECU to adjust then switched it to map 7.

Wow my car really does shift on map 7. Car in question is an Audi SQ5, map 7 is claimed at around 380bhp / 750nm I don’t know what it’s actually running at but it pins you to your seat, the torque it kicks out is insane, hits 60mph in around 4.5 secs. This 2 ton SUV will now give most cars a good run for their money with this box fitted.

Only little niggle I have is I don’t really think 7 different maps are necessary. Map 1, map 4 and map 7 is all I need. Can’t feel much difference between maps 1-2-3 and maps 6-7. Map 4 is a good balance very smooth, map 7 slightly jerky at times like it’s always raring to go.
