are u still having trouble reving over 4k? if so what does it do , does the motor just fall on its face, or is it starting to miss and pop and bang?
if needed i can post a video of what it sounds like if the plug gap is to big and the ignition system isnt upto the task.my friends car i tuned would have the same symptoms at around 4,500 it wouldnt rev past there at all and would bang and pop.
went from .032 plug gap to .022 and its been flawless ever since.
what intercooler are u using is it something out of a junkyard car?if not whats the core size ?
genrally ur going to want something in the 32x12x4 range though a 32x12x3 will work for moderate hp levels
remind me again what car this is in and what trans ? 3:55 or one step down would prolly be a really good match . i do recall u saying no more then 5 psi in first gear. once u do a gear swap u will get alot more boost in first
