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!

After doing some research on tuning kits & talking to the guys at tdi, we decided to go ahead and purchase our first kit for a Range Rover Sport 3.0 HSE. The purchase was easy and it arrived very quickly! On opening the box, the equipment was well packaged and there was also a detailed photographic instruction manual included which would prove to be helpful. We set to work on the range rover sport and it took less than 20 mins from start to finish - wow! We opted for the upgraded tuning box which allows us to control the box via Bluetooth on the mobile phone. This is very good as we can control what setting we want the car to be at which is easier than lifting the bonnet each time. Once the kit was installed nearly and secure, we put the car to work and slowly increased the settings over a period of time that was suggested by tdi. We have done some long journeys since the install and can confirm that the mpg is much better and also the acceleration lag that is typical on a range rover has become much smoother and far more responsive. We have since installed these kits on several other range rover models with excellent results and happy clients. We would highly recommend tdi tuning boxes as they can easily be removed if the car is going into a dealership for work Still under warranty. Overall - 10/10 & a pleasure to deal with the guys at tdi!

Got a 2022 samyoung musso pickup 180 bhp 420nm stock all of 5 minutes to fit the tuning box the power is a joke maybe sitting at 500nm 235bhp cruise at 120mph rocked of line put you toe down your up 90mph in crack did not want a remap for the warranty ,, Connect to my phone1234567 maps over the moon
