going in for a re-tune next week and i am going to throw in a fresh set of TR-6 plugs but i also added a ecs meth kit so not sure if i should leave the gap at .035 or change it to .032 .033 what do you guys think?
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.
