What gap on plugs for more boost and meth?
What should my gap be for meth and higher stock turbo boost? I have the one step colder plugs. I seem to be maybe getting a bit of random misfire through the rpm band.

usually if your getting a miss you would want to close the gap a bit depending on how close it is to begin with

Thanks for the quick response, I am going to go check the gap now. I usually hit 28psi.
