Lean codes in both banks.
I have an aggressive tune in my car(LS1 Edit) and it makes great power there. The problem I have is that when I run pump gas it throws the lean codes for both banks. When I run 112 octane the codes don't resurface after I clear them. Does this sound normal? I have no problem running the race gas seeing as the car makes the best power where the timing is at. Is this normal or somewhat? Thanks for any help. I know I could back the timing up a bit, but I wanted to keep it where it's at.
