Hello, my name is Kacper, i have my own company which specialises in ECU modifying, car reparing and trading. I drive Audi A4 B6 1.9 166 hp, A6 C7 2.0 TDI 205 hp (DSG :<) and A5 3.0 TDI 340hp :) I want to increase my knowledge about ecu modifying there and just learn new things. I hope i find there what i want :)
