I think the main thing that makes the 94-95 GT a little slower than the Fox GT is the weight difference and the restrictive EEC in the 94-95s. As for 94-95s not making power til after 4000rpms, thats rediculous because mine pulls hard from about 3000rpms til about 4800rpms....I shift at about 5300 which puts me right back in my powerband for the next gear.
