I am getting slightly bigger turbos, i will modify my current tune a bit, but i do not know how these new puppies will respond. I am running e85 with some very aggressive timing. I want to reduce overall timing a bit to begin with, to get my boost profile right. So, i will reduce only the last column, at the highest load? Whould that be good enough?
Good enough for what? So it doesn't blow up on the first pull? With E85, i doubt you'll have any problems even if you don't touch timing at all.
If you didn't numb KR the ECU will make sure you dont run too much timing. Either way, though, you'll want to tweak timing *on every cell* based on logging, not guessing.
