Finally put my car on the dyno for a tune. I have a 2001 Cobra with D1-SC w/ 3.4 pulley and built shortblock. The problem I am having is the power climbs up to 5200rpm and then it falls flat in its face and the curve goes straight down., but its making 15psi of boost and holding strong on the boost department I have 03 cobra pumps and tanks with Kennebell BAP and 60Lb injectors with SCT2400.Also my spark plugs are AUTOLITE 103 gapped at .030
I thinking its a ignition and spark issue since I have plenty of fuel and boost.
it does spike alot on its way straight down from 5000rpm. I'll try to post a pic of the dyno graph tonight after I get off work.
