acceleration delay...

Ive got a super 40 catback, header, k&n fipk, 60mm TB, accel coil, mallory wires, and ngk plugs. For some reason if i am driving along at speed, then mash the pedal down close to WOT or all the way to WOT, it hesitates, slows down, then comes kicking in like a bat out of hell. Why is it hesitating like that? Anyone know? Do i need to screw with the computer? Just wondering why it bogs down. Figure this pile of parts should be a great combo, and it is, but only after it hesitates first haha. Any help would be great. Not sure what im missing.

Mine is starting to hesitate from a stop sometimes.

Feels like its starving for fuel, id imagine now is about the time a fuel pump would take a dump on me.

Such a PITA.
