I keep getting knock retard really bad. It always always comes on in the 0.56-0.60 2200-4000 RPM range. I have tried to disable burst knock, please let me know if I did it wrong. I have tried bringing in power enrichment early. It does not do it in open loop mode. Any help would be greatly appreciated. Stock 5.3 with built TH400 trans in a 89 chevy truck. Motor mounts are brand new. 19-09-13 08-54-49.hplStep 10 Power enrichment.hpt
