I'm no expert, but don't see why you would close the gap unless it has a misfire. How much boost?

.035 worked fine for me at that boost and running meth.

I'd leave it at .035 also, decreasing the plug gap also affects timing.

I originally had mine at .035 and when I upped the boost to 13psi we were getting a mis-fire so we closed the gap to .032. So .035 does not work all the time.

Also I do not see how closing the gap .003 is going to affect timing.
