Hello, I am new in the forum but have a small experience in ECU tuning. Done my car on my own (Audi a4-b5 1.9TDI 90 hp engine converted to VNT turbo GT1749VA+ 216um nozzles got around 150HP) and some other stock cars mainly VW/Audi. I hope I could learn new things and help others who have less knowleadge. Have a great day!
