Okay Judge - I know I've been rude to you in the past, so I'll try extra hard to be polite here. I've seen in 2 threads now you and Terry saying the 2.5L PCM in the 3.0 is a bad idea - and the 3.0 should be repinned and used instead.
My uneducated persons question is, why would the 3.0L PCM spark curve work any better for a 3.0 with monsterously high compression and 2.5L cams than the 2.5L PCM would? I would think both would be more or less equally "sub-optimal" and to get the real "perfect" curve would require a cutsom chip?
Is optimal spark timing more dependant on displacment than on cam profile and fuel curve?
Just FWIW - David Z' Mods (below), no chip & stock SVT PCM, stock injectors. Not bad power for a sub-optimal setup IMHO.
