to put it straight Lithium, The 450kw was on race fuel at autosalon with to4z .82 rear 24psi, was making 430 on pump98. Just its really bugging me that it seems stuck at 400 plus. In all Honesty it should crack 500 plus @30psi one would think engine sounds great. Did a comp test evrything is good 134,134,134,135,137,134. Thinking either LS2 coils or okada what your thoughts about the situation?
