getting a tune on the 20th so looking to get it before then, please someone help me out. i wanna break 270 with a 3in pulley

 

You DON'T need that to break 270. You also don't want to know the throttle differences these do to our cars.

 

i got the ported sc and the raw 3in intake i figured why not get the ls4 tb its cheap and its easy hp.

my car made over 250 before the exhaust ported sc and intake so i figure with the tb and a good tune under it i should break 270.

and i got the spacer already hahaha

 

Meh. If I were you, I'd just get the stocker ported.

But hey, your money. Good luck hitting your goal.

 

thanks ill try
