Fitted a tuning box to my 2018 Toyota hilux, I’m up around 5-6 mpg, very simple to fit 10 mins max Great product, great service, just a tip make sure you keep wires away from heat source with the cable ties supplied, my own fault So melted the wire harness so just a tip to check once installed. 10 out of 10 guys 👍🏻

Where to start? A bit about me. I’m 40 now, I’ve always had fast(ish) cars, fiesta 1.6sport, mr2, civic vti, z3 2.8, rx8, Impreza Wrx, and last year I owned my dream car - a golf R. Also last year had my first experience of people trying to break in to the house to steal the car. When it happened the 2nd time in a week I thought for the sake of the family, house and my own mental health (I tell you the paranoia is awful!) that the golf had to go and I’d get a boring car that nobody would want to steal. So I traded in the golf for a..... Nissan qashqai 1.2 turbo. Lol. The car is great (toys wise) but absolutely gutless. It’s engine is too small for the size/weight of the car. In a hilly area it’s constantly changing gear to keep it going, change too early and no turbo spinning to help propel you. Was looking into “proper” remaps but couldn’t face the embarrassment. Looking at these boxes- very mixed reviews on forums. However, 30 day money back promise (bought on credit card, just in case) and I fitted it yesterday. Now the car isn’t fast, it never will be, I wasn’t expecting it to be BUT with this fitted it 10x more driveable, that’s all I wanted. For me this box works as I wanted it to, it makes the car “nippier” for sure and picks up the pace a lot quicker than before. I’m still only on setting 4 too. I’ll try higher settings for sure but it’s already done what I wanted it to do. Thank you

Customer service is second to none. Queries are quickly answered with total professionalism. Will be recommending them. The box works a great on my Audi A5. Thanks guys

Superb box makes car so much more responsive

Just installed a tuning box on my 2017 VW Touareg 3.0 R-line. Was skeptical at first but noticed an appreciable increase in power and turbo response as well as my usual combined mpg went from 33 to 38, even in setting 4. Happy customer so far!

Bought a tuning box and definitely say it does what it says on the box, so if you want to get more mpg or power this is the best option. Cheers TDI Tuning

Have to say a thank you to TDI Tuning, took the leap of faith on a Infiniti Q30 S and it really did transform the car ! After that I purchased another one for my wife’s GLC 350 and now that’s a real monster, so I can definitely recommend them as a company and as a product!

TDI tuning have worked wonders on half a dozen vehicles for me, from a TDV8 Range Rover Sport, a BMW 520D and most recently and with the most dramatic result my Audi S4 Avant 3.0 TFSI V6 Supercharged. Fantastic performance increase with notable economy uplift! Thanks again Steve and team, as professional, courteous and welcoming as always!
