I was pretty disappointed when I purchased the FAST 102 and LS2 throttle body only gained like 14 RWHP and 12 RWTQ on my cammed Z.
I am very happy now after the TFS 220's as i am sure the stock intake would of held me back.
Cost wise I should of done the heads first, yeah they cost a $1000 more but i got 50 RWHP.
