[QUOTE="hatchke, post: 16882390, member: 185172"] Went out and was testing some 60-130's in Mexico and the damn thing was breaking up really hard in 3rd/4th around the 6k mark. I adjusted the plug gap on my TR6's to .025 and it ran/pulled MUCH better after I found 3 of the plugs were gapped pretty loose. My dyno charts show a little bit of the hesitation and Blankenship suggested it was probably just the plugs. Ran .5s faster after but still breaking up pretty hard around the same mark. Do I just keep tightening the gap down further than .025 or am I missing something here? From what I read, the TR6 seem to be fine around this gap for most on E85. For reference, I made 690whp at 20psi on my Whipple 2.9 with E85. I'm running a decent bit of boost but this setup isn't anything crazy. I didn't see many people running much tighter than .025 but I guess i'll roll down to .023 next and see how it goes? [/QUOTE]
