If your OTS 91 tune can't handle driving to another state or isn't conservative enough to not blow the motor up on the octane it's designed for, it's not a very good 91 tune.
It's a pretty simple concept.
Nope, just saying people are being silly running 93 for "safety." It's an OTS tune, it should be conservative.
How often do you track?
Do you think they're giving you bad gas in Florida? Why even trust the 93? Go straight to GT 260 or run stock boost on ethanol if completely minimizing the risk of detonation is the goal.
I'm not getting into the debate on tunes and octane except to say that if it gives you peace of mind and you don't mind spending a little extra for 93 that's all that mattersYou didn't answer the question.

I'm positive Ed would say to not run lower octane than you were tuned for.It's pretty common to use a little more conservative tune for a track car than a daily driver. I'm not sure what the controversy is.
And also love to hear Ed's thoughts on whether it's OK to run 91 octane with his 93 Oct tunes. Or any actual tuner for matter. I've yet to meet a tuner that gives the ok to run 91 Oct on a 93 Oct tune, as the other poster is proposing.
I'm running a 93 tune, but I put 94 in it. God bless Petro. Ya'll in the states don't have this wonder juice. But you do have Riley Reid so.... I guess it works out.
Appears to be grind marks from balancing. Tho it looks a little rough, its normal to see material removed.
Normal, that is part of the balancing process
