Just installed 75 mm Pro Flow MAF, 65 mm TB, and cold air fenderwell kit. Also installed Underdrive pullies. Installed Off-Road H a few months back. Of those 5 mods, what kind of gains am I looking at? Sorry for this newb sounding post, but I'm curious...
-I got close to 15RWHP from my CAI (dyno proven) and only about 8 from my pulleys... MAF only really helps if your engine needs that much air... otherwise, you could not gain any, or loose some... the O/R is a little low, granted you're getting rid of the restrictive 4 cats, and I'm assuming new mufflers as well...
