new fuel pump ~ now misfire

[killergst121]

Heres what I did:
I just in installed a walbro fuel pump because my stock one died. I copied this descirption from the store I bought it from, Extreme Motor Sports ~
Extreme Technologies In-Tank Fuel Pump [EXM0228] $149.00
This unit has much higher flow than the stock unit (75 gals/hour vs 48 gals/hour) and is an exact replacement. Includes all the parts required for a perfect fit. For turbo models only.

Heres what I've got done:
big 16g turbo ported
greddy s-type bov
adjustable fuel press. regulator
3' intake pipe
manual boost controller
boost and air/fuel ratio guage

Heres the problem:
After I put in the new fuel pump my car misfires when I accelerate fast over 2300 rpm. What is going on?

Possible spark blowout from too much fuel. Lower the pressure. Try about 40psi.

No , he has a 2g fuel pressure should be set @ 43 psi with the line off.
