I just put a set of patriot 243 heads and a thunder racing 594 lift with 226 duration and 112 LSA. Other mods include SLP lid, Smooth Bellow, Kooks Long Tube Headers. Before the swap I ran a 330 HP dyno and now I am only getting 333 HP. It is sending codes for engine misfire and I've also changed the O2 Sensors, TPS, and Map sensors already after it sent those codes but did not change anything! Any help kind of dissapointed on this was realling wanting to break the 400 barrier.

First it showed MAP Sensor Failure, O2 Sensor Sensor Failure, TPS Failure, Engine Misfire (Critical Performance) and a couple of U codes not to knowledgeable about that. I live in Kuwait so there's really no one inclined on this.
