I have .025 with my current COP setup but I think they might need knocked down because they seem to have a really bad miss intermittently around 31psi right now.

I haven't used the ARC2 in probably 8 months. It went bad and I have been too lazy/busy to call them up and ask for a new one.

I've changed mine a few times but didn't pay close attention to the straps. I'll do that next time. I have to run .019 on stock ignition with BR8ES.

I recently changed to BR8ES @ .025 from BPR7ES at the same gap. I noticed a big change in throttle response and top end just from the plug switch.

I looked over the head and combustion chambers when we pulled the head off for head studs. It's amazing how clean they look after 6 months of E85.
