Hi, i have a 99 gt with 4.10's, tb/plenum/cai, subframe connectors, slp cat-back, diablo tune, steeda short throw, sway bar, eibach sportlines, and i'm piecing together a NX wet kit. Well as soon as i get off the throttle it kind of "bucks" a little while decelerating. Its not really too hard but it is definitely annoying. Also I've noticed that if i kind of dump the clutch it will stutter a little. its got 91,000 miles on the stock clutch that is beat on somewhat regularly. oh and since i'm here i was wondering how well my (well maintained) stock 4.6 can take 8 psi and for how long (its definitely my only car)

 

first check the obvious, fuel filter, IAC lol. if that doesnt solve it. we will go from there
