Engine/Supercharger
Does porting make such a huge difference? I got Airaid to 2.5 upper 9.5 lower cat delete, SS headers x pipe to stock ex. ice box, bigger hx, d3 lid spacer, custom LS9 heads, GT9 cam. Some other stuff can't think of it... What would be better? Port TB or blower snout? or both? Why?
Thx
