Misfire issue

[chetvram]

Hey I been through 6s to 8s with my spark plugs now I am running ngk 7s at .28 gap. The problem I am having is my car with drive with full power if it is real cold but as soon as it warms up it wants to misfire a lot when I get into the throttle. Timing has been checked, new plugs added, Boost leak tested, coils tested, MAF tested aswell. I have also tried lowering and raising boost and it doesn't make a differece. Any help is appreciated.

I noticed you have DSMLink, and a PLX WB O2. What is the A/F ratio? Also after the car warm's up is it RPM specific, or just when you go WOT with the throttle, or just after its warm, and you touch the throttle at all? Are your cam angle, and crank angle sensor's working properly?

Well guys after a very long time we solved this misfire problem yesterday by changing out a plugged fuel filter. It pulls great to redline now and doesn't break up at all.
