i have this done on a 95 se atx and it sucks....i haven't had time to change it back to an original unit yet. upon starup, if i rev it, or anytime it is cold, it stutters and almost dies. the idle is not too bad but after everything is warmed up, it is a lot better. but i DO NOT recommend anyone doing this, b/c it is a waste of time and just will fu(k up your engine.
