Pokageek said:"btw ...... IMHO, the worst bang for the buck spent is a catback." Agree.
"Others that don't do a lot are tb" Disagree in my case after my cam and stuff the TB made all the difference in the world. Maybe it was the bottle-neck. Going with the Ford Racing 65mm was night and day. The new electronics didn't hurt either.
GEARS GEARS GEARS. K&N panel filter doesn't give you any HP either.
The tb is gonna be more effective for you for sure with your mods.
Look at his mods ...... he ain't movin any air!
