Car is fairly new to me so I'm still figuring out the nuances with it. 87 GN FMIC, Exhaust, headers, CAI but stock internals. Running safely at 9-10PSI boost for now, ScanMaster is showing 800-820 at WOT but I've seen up to 6.3 degrees of knock retard:redface: Why should I see any at that level of boost Could it just be artifact from a noisy shortblock? Hot idle oil pressure is low(like 8-9) so main bearings are suspect More good news on a 'new' car...
