Hey guys, a little help here please...

<-----------------------------------------------

and I punch the gas the car pulls great up to about 4500 (estimated) RPM and then jerks and drops off and then continues on normally.

I'm running the stock fuel pump, injectors and no electronics and I'm not dynoflashed yet. I was on 91 octane and a bit of octane booster.
