Noticed some detonation/pinging the past few weeks... winter blend gas probably didn't help. On a hunch decided to remove and clean the MAF... worked like a charm & detonation is gone. Throttle response also seems better & idle is smoooooth.
Received my 91 tune from Justin last night and got it installed. I have not had a chance to drive it yet. Justin feels confident that this will eliminate the detonation issue.
