So far so good. The box has certainly made a difference to the way the car drives, it is smoother and pulls better through the gears. The extra torque is noticeable especially when under load, such as overtaking uphill. I haven't played with the different settings, just left it on the factory shipped setting, but may see what difference the higher settings make. Overall very happy with the tuning box.

Well over the years ive had a fair few cars,some remapped,always been happy with the end result.This time round i wanted something that gave the same results but that i could remove and control.so the search started,and came accross tdi tuning.ive always been sceptical of tuning boxes,but tdi tuning have converted my opinion.fitted one to my honda 1.5t 10th generation,drove it for 30 miles with the box set to level one to let it settle in.I then took it for another continuous run of 20 miles,then switched it up to level seven,My god.......im over the moon with the power increase,smooth and well delivered.definately opened my eyes to another avenue in engine tuning.its the best money ive spent in years,and ive spent a pretty penny over the years i can tell you! If you havent bought one yet or like me was a bit sceptical of these boxes,tdi tuning put that to bed.well done guys,love it Regards richard hatter Civic 1.5t 2018

after reading up on tdi tuning box i purchased one for my nissan pulsar 1.2 24 hours later it was installed the added performance astounded me i ran it for a couple of weeks then installed it into my wifes juke let her try it out for a couple of weeks then asked if i could put it back on my pulsar the reply was NO so i had to get another one for myself 24 hours later my new box was installed i can only say the added performance and improved fuel consumption on both cars far exceeds expectations thank you
