I first installed my TDi tuning box onto my Jaguar XE 25T nearly 2 years ago and have been really happy ever since. However, recently there has been a thread running on a forum that I participate in where someone had installed the very latest version on their 25T XE, it immediately became apparent that the latest "map" for the XE gave another 10hp and almost 20ftlb of torque over the "map" installed in my tuning box. Cut a long story short, I phoned TDi and spoke to Alex (Monday morning) he told me to send my box back and they could install the latest map for me. Box removed and returned on Tuesday, they received Wednesday morning and by that afternoon it was on it's way back to me, I received Thursday morning. That is absolutely phenomenal Customer service. More important are the results of the new updated map. The car has found found a new lease of life, mid range torque is staggering, it really is like driving a completely different car, on a motorway I just have to touch the accelerator and it's off, simply amazing. A huge thank you to Alex and all the guys at TDi tuning, you have made a long time Customer even happier, I will continue to highly recommend you to any person I know with an interest and passion for cars.

Quick and professional service and works a treat. Instructions for installing were good and had no issues fitting the box.

Excellent service, equipment, advice and support. I had a TDI Tuning box already In my Audi TT and it was excellent and then I contacted them to get it reprogrammed to use in my new car, Jaguar XJ L 3.0 Bi Turbo Diesel V6. The service was absolutely fantastic and the process to install again was simple. It’s made a fantastic difference to power and torque and the difference is very noticeable and acceleration smoother. The technical support has been excellent and the staff very patient and helpful. I totally recommend TDI Tuning.

With being a previous employee at TDI, I knew first hand the effort and work that goes into the maps, which meant that when I changed my car to the new GR supra, it was the first place I wanted to go to get a bit more oomph out of that great B58! For such a capable platform it has really added that extra zest to the engine where even in normal mode, the turbo and induction noises were much more prominent! With the car also still being under warranty it was a no brainer to start the tuning journey here where the box can also allow for some further light mods to intakes/exhaust and the map can be adjusted to suit! All in all, as a customer, I can’t fault my experience, where they were even kind enough to take me out to get some 0-60 times (with a 0.5 second reduction in the highest setting!) and I look forward to getting some more miles under the new and improved supra’s belt!

Had a chip installed on my 2017 Jeep Cherokee 2.2. Service was amazing and fitting was done at a very high standard. The car has a noticeable increase in power and I can see a 25% increase in my fuel efficiency which is fantastic. Told my insurance company and my premium only went up £22 for the year. A bargain considering the £000's you will save in fuel over the time of using the car. Would highly recommend this very professional company. Thanks TDI-Tuning !!

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
