Nitrous?

[03stangGT]

I'm seriously thinkin about gettin nitrous for my car (03 gt). People on another site did nothin but bash Zex but seems like a really nice set up. Anyone here use Zex? I'm planing on a 100 shot. Also if I plan on doin anything more than a 100 shot, I'd need to upgrade the fuel pump correct? Before I had most of my mods I ran a 14.4 at 99.3, but that was with no quad shocks ( I had insanely bad wheel hop, sounded like my car was gonna break appart). I havent got to go to the track lately I'm hopein on 14.0-14.2. With a 100 shot do low 13's sound reasonable? how about high 12's? My current mods are... Mac offroad H, 2 chamber flowmasters, k&N, steeda underdrive pulleys, Steeda timing adjuster, steeda sport springs, jd's performance upper/lower control springs, 3.73's, and a pro50 shorty shifter. sorry about the book, any opinions will be helpfull, thanks
