I've installed my new injectors so I can raise the boost and everytime I want to boost past 16psi, I get misfire in the vtec range. Did a run at 14psi and check the plugs, nice brownish color. I'm running a MSD 6AL with a Balster 2 external coil, heat range 8 plugs. They are gap .35, going to gap them at .28 and if it still does it, going to try new plugs.

Have I overlooked something ?

Instant message enable No need to sand the electrode, since I got 20 in stock I've put new plugs.
