was thinking about adding a 70mm bbk tb and plenum to my "04 gt
only mod so far is k&n caik
; tune, exhaust, and gears to come this spring/summer. POSSIBLY new plugs and aftermarket COP's as well
my question is can i truly expect to see some added throttle response or HP with the aftermarket TB and plenum, or is it a waste of time and money if not going to some type forced air and upgrade in MAF unit?
any help greatly appreciated-
