[droptopford 5 0]

here's the situation... i know my car is slow to begin with, but aside from the fact, my bud with the same car isnt this slow, so what gives... i have a 94 GT auto vert. when climbing from a stop to about 20 mph(about 2250 rpms... my car is dog slow(understandable to the auto and 2.83 rear gears. then it really wakes up from 2250- 4000 rpms, but above 4000 rpms, the car just doesnt want to climb to 5500 to the shift point when in WOT, i have new FMS cap and rotor, new Taylor wires, bosch platinums, advanced timing (around 14* i think) and thats it for electrical/ ignition...what's wrong??!!

I could be wrong but I think the stock intake is pretty restrictive in the upper RPM's
