what else to do
what else to do hey guys i bought a stock 00z28 this past summer the only mod it has is a catback borla. i bought some hooker LTs and plan to throw those on in a couple of weeks i also did the air box mod so buying a lid is not so necassary, lastly i plan to port the throttle body and buy ls6 im if i can get one at a good price then get tune in spring, my question is what else can i do do get some bang, i do not want to go internal right now so basically all bolt on stuff, but the only thing else i can think of is an underdrive pulley, do those acutally work(ive heard they are not great in the long run) so any other free mods or bolt ons im missing, or some ways cheap ways to get some hp? thanks.
