Throttle Body Spacer: Smooth vs Swirl

[Blue95]

Well factory spec on fuel psi is 9-12 psi, 12 is barely enough for a stock engine let alone with any mods so increasing it even a half a pound or pound will help alot, the computer will adjust some but not alot, MPG will go up if anything, deffinately not down.
