Throttle Body
I think i might drop in a new throttle body. seems cost effective compared to some other mods...$200 for 15-20 hp.
what is the stock throttle body diameter on 01 Screw 5.4?
since most replacers look like 75mm. Just want to make sure i am going to improve from stock
while i am in there should i add a throttle body spacer (few HP gain)? is it worth it?
any thing else i should consider at this point?
oh..the K&N FIPK rubber connecter to the stock throttle body...will it fit a larger throttle body..or do i have to change rubbers (haha)

HI!... Stock TB is 70mm. Actual gains on a basically stock truck are about 5-7H.P max at the flywheel. Remember you MUST port the TB ELBOW to match the new larger 75mm TB. If you don't do this you will gain NOTHING!!!!!!
