yeah what i can tell about it, if you have a good tuner it will be a good friend also because you will be in contact during the prosudure CHIPTUNING. so he can support you or make chenges if you need. so i know what you mean. i do Chiptuning for a long time. and only think i see is... the chiptuning going down. prices are crazy because i cant believe if some one tune a car for lets say 80.000 euro and he ask for tuning 150 euro????? or sell a RS6 2019/2020 file for 40 euro i can understand that thinks but you have to other wise they will think iam crazy because every one do it

and repect for all, but it my way of thinking
