Track configuration is also going to be a factor at some point. Longer tracks should be dominated by the higher exhaust ported 01 if both cylinder options are jetted to satisfaction. You just can’t beat .040 higher exhaust no matter what you do, it’s straight up more RPM range equaling more top if geared for it.

110 fuel would help save the 01 from destruction but as noted above it would definitely be the end of any reason to hang onto the 99. Who’s to say that once 110 is offered the 01 tuner won’t just lean on it even more gaining power until it again moves into detonation range.
