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!!!!!!

 

hey...

nice STATS on your image gallery...

pretty fast huh?

5.8?? man thats smoking

it seemed like i was about 16 or 17 seconds counting in my head...ouch!
