Over a week ago I picked up my tuning box for my ford s max 1.8tdci. Plugged it in and drove home what a big difference the response on my Excelerator was impressive. And my box was set only on middle setting. I've since moved up one more setting again I was very happy. Economical with more power what else can I want. Thank you great service.

Fitted one to a Mitsubishi l200 , it has eliminated acceleration lag completely and power is way up , was sceptical when I bought it but we'll worth it , definitely works

On an old lt35 vw van work horse it has transformed the driving experience! Pulls so much better in higher gears so looking forward to the increased fuel economy!

Just fitted my CRTD2 Twin Channel diesel tuning box to my Mk3 Octavia VRS and the results are already fantastic on the "Optimal" setting. I can't wait to try the higher power settings soon! The communication from TDI Tuning is excellent and they are more than happy to answer any question you have about the tuning box. I would recommend TDI Tuning to anyone wanting to see genuine results from their car. Thanks TDI Tuning!!

I've had a number of the tuning boxes and they ALWAYS deliver on both power and economy. Tdi also proved today that they're great when you encounter a problem. Thoroughly recommend.

Brilliant service from the start. The box works brilliant. Much better than the previous box which was from another well known firm. Beginning with a D and ending with a K. The power delivery is much more smoother. So I'm well pleased with it. And unlike the previous box I can transfer it to my next car as it's based on much newer tech compared to the other system. Many thanks again TDI Tuning. Job well done. Keep up the great work.

I fitted a twin channle box to my 2.5 hilux there is definitely less turbo lag much more responsive and defiantly more tourque when going up hills

Fitted tdi tuning box to my 2015 transit connect, instant difference to the power/torque the lag has gone just keeps pulling through the gears, much more smooth running, money well spent, customer service was second to none,

Great staff and really helpful. Having the stage 2 box fitted to my VW Crafter sports van has made such a difference... With it set in the middle mpg has risen to 34... And the power uplift makes easy driving.... Many thanks...

Fitted my CRTD2 box today and WOW! I have a 2013 ix35 with 134bhp & 320nm and this device has transformed the car, I can fully believe the claimed increases. Fitting was a doddle, actually took me longer to cable tie everything tidily than it did to plug it all in. My main reason for fitting was for the gains while towing a caravan which I will be later in the week so I'm looking forward to seeing how it performs then. If you're thinking of buying one do it now and spend longer enjoying the results! Thanks TDI Tuning.

I only ever buy the tuning boxes from this company, and recommend them to anyone. They defo work! The customer service is excellent and ive had their boxes on a few cars over the years and i get sick of people who dont have one telling me they dont work! Thats untill they have a drive of my car! Then they buy one! Ha

Very professional service ,and they have a great knowledge of there products. The twin channel box I had fitted has vastly improved my car to the point I think I'm driving a different car. Thanks guys for looking after me.

Got my box for my insignia tourer and straight away could tell the difference with power and getting good mpg out of it for only been on a basic setting aswell, would suggest to anyone thinking of getting on.

Great service from tdi tuning...messaged me back without fail whenever I needed help. Fitted my CRTD2 twin channel box to my bmw 335d,instructions were clear and easy and the difference its made is amazing!

My Range Rover is smooth as silk and pulls even more like a train with a great return on MPG ave 33mpg before chip 24mpg , can not believe the difference
