I asked some questions of the TDI team to clarify a few concerns and got positive responses to each within 24 hours. I then bought a TDI box, which was fairly straightforward to fit. The App connected and the various settings were tried. I generally leave the box at setting 1, which improves the mpg or kpl :o) Have since asked further questions that have also been answered quickly. A great product and excellent support.

Fantastic love it . So much fun

Bought the tuning box with Bluetooth access for my 2016 Audi A5 3 litre diesel. Took away the lag immediately, made it feel so strong in every gear and the power on tap for every need. Definitely recommend, car feels like it doesn’t run out of steam since having it.

Highly recommend this product. Bought one for my Abarth 595 base and it noticeably improved the daily driving experience. It pulls from standstill with a more linear delivery (in city driving you feel this more), and I gained at least 10% in fuel economy. Tried all the 7 settings but setting 4 (default) is the best one in my opinion for the best power boost/economy balance. Had a issue installing it due to so many Abarth variants, but TDI Tuning customer support were amazing and responded in no time to help me figure it out! Great product and customer service!

Purchased box for my 2019 Audi S3 the power and fuel mpg increase is substantial Highly recommend

Great postal delivery and value for money on this device. I've been telling everyone on the Elantra GT forum about the remarkable difference this turbo tuner has made in my 2020 EGT N-Line! Went from being a mild disappointment to near-Veloster N performance. I don't even use Sport mode, anymore. The acceleration in all phases of driving is nothing short of exhilarating! Please, keep up the good work! EDIT: Hyundai GDI 1.6T powered vehicle owners need to swap out factory coil-overs, or *nothing* will stop the misfires into safe-mode. I recommend MSD Blaster Series Part # 826943. Get that, get TDI and you're all set for a great (almost scary) driving experience.

Was averaging around 10 km per litre on the hwy for our 2015 Isuzu MUX and between 5 and 6.5 km per litre when towing our 2 7t caravan. After fitting the TDI Tuning chip we now average around 12.5-13.5 on hwy and between 7 and 8km when towing. There is also a considerable increase in torque across the rev range but particularly in the low and mid range which is great for towing. The tachometer used to sit around 2250rpm at 100kph and now sits around 1800rpm. Very happy with the chip and the customer service I received from the UK head office. Only wish I had bought one sooner!

Very professional, and quick!

Totally transformed my LDV T60 Utes performance, No accelerator lag on take off and good holding power on the hills. Bluetooth great once I got it sorted, Operator issue not product. Tows tandem trailer with ease compared to before TDI was installed. Install was simple. Delivery time very good from UK to New Zealand in a matter of days. Very impressed, Thanks.

Great product. It REALLY works. Great customer service. It is just as easy to install as they say.

Very helpful and a cracking product

Seems to work well on my TT, I suppose the instructions could be a tad better, took a while to locate the correct plug! Thanks

Knowledgeable, helpful & Freindly staff. Great job, Great product. Lee Essex

First class service. Excellent product. Tuning box works perfectly

The ordered tuning boxes have not been built in yet, so sorry, no feedback or result on the tuning experience as such. However, when it comes to your expertise and customer service, 5 out of 5 stars.

Way more power.

Quick shipping, very helpful staff, and a great little product, would highly recommend, fitting is pretty simple and easy to remove (car depending). Dont be fooled by the cheap ebay alternative they are not the same, I tested this to improve throttle response, and it works really well. Good work

Used my old box which they retuned. Excellent service, excellent performance!

Quickest install, huge power gains and on setting one and when my car is in ECO mode I actally got a 5-7mpg increase! Highly recommend this product! Very smooth power transition between gears no hesitation or jerking, suits the car very well!
