4,500 rpm miss fire on and off load

[Natedsmeclipse]

hey guys i am getting a miss fire with my turbo 420a it happens around 4500rpms and it happens if i am just reving it or i am on the road. i have changed the crank sensor, tps works fine, new cam sensor, i am also run AEM FIC contorler on the car so i can see that the TPS works just fine. i am running out of ideas so if any one can help it would be nice thanks.

Are your plugs gapped correctly? Try new plugs, wires, coil pack?

Same problem with my 4g63 gsx... spark plug wires seems good, but internally toasted... new spark plug wires and boosted again!
