okay lets c where should i start. ive cotemplated almost every mod for A 06 MUSTANG. as for cams. none of the cams on the market are picking up more than 40 hp max. i have a friend with underdrive pullys, intake, full exhaust(longtubes) comp cams, custom tune and hes makin 352rwhp. forced induction on a 3v will make 400rwhp VERY easily but of course is $$$. the only cheap way to go is put a N20 kit on and get a very safe rich custom tune. and you will never hafta worry about a thing. people are scared of n2o because alot of guys are dumb and just put it on with no tune and spray the hell out of it. n2o is actually very safe with a good tune and not goin through 5 bottles a week!
