This is a question for the turbo guys. If you are going to start from scratch and pick an ecu for a turbo setup, is there one that works better than others? I have not got to play much with the gen 4 ecu's much, just the E38 a little. I noticed is has controls for boost. When I was looking at the E38 it showed that no enhancements were available, is this correct? Or are the Gen 3 with 2 or 3 bar enhancements the way to go?
