I'm currently having the worst time with ECUTek. Apparently my Turbo Pressure Ratio map is all sorts of messed up. Their customer service is abysmal at best and cant provide me or my tuner any information on the matter. Has anyone gone from ECUTek back to BM3 without loosing their ECUTek license? I want to go back to my previous tune for an event that is nonrefundable.
