how bad is it running lean?
I brought the car to a dyno today and they could only do 1 pull because the cars running lean. They said its not good and they didnt wanna blow it up. Detonation? They said they needed to pull some timeing and it was because of the aftermarket maf and maf ends are letting in to much air. Said it was pinging alot. Also descreened. I couldnt have them do it today im fing broke. How bad is it running lean?
