[QUOTE="Screamin_Heaton, post: 7676378, member: 78586"] Like the title says I would just like to know what gap all of you guys have found best that works with tr7ix plugs and 17psi of boost. With the new 63# injectors (39s are giving out--leaning out past 5krpm with constant fuel pressure)my tuner thinks I should see 520 easy with my setup. I am running a ported eaton and lately getting some idle hiccups, burps, and occasional midrange bumps with the tr6 coppers gapped at 32. I have read through a lot of different threads and seen a few different opinions. My main question is...should I be running a smaller gap than 32? Also I've seen a picture of a special gap tool for iridium plugs. I planned on picking up some feeler gauges, but is this gap tool better for the tr7s? If so, where can you pick one of those things up? (Advance,Autozone,Napa?) [/QUOTE]
