302 preformance
hey i have a 1990 f250 5.0 5 speed. i put an intake tb spacer headers and dule exhause all the way back. is my computer keeping these mods from preforming or do i need a chip? if not a chip would roller rockers and a "computer compatible" cam work better?

The TB spacer is a paperweight.. not worth any gains.
The exhaust will deliver gains but the cam is effectively governing the motor to an artifically low output, and upgrade here will produce dramatic increases now that you have an improved exhaust system.
