Exactly. WMI is the key, plus combined with lower compression ratio pistons high boost is no problem. We have our Time attack tC tuned at 34psi on pump gas with WMI. I'm not sure what my ignition timing is, I haven't looked at my map... I leave that up to our tuner. It is tuned for MBT ( minimum best timing), any good tuner tunes for MBT where any more timing results in no power gain... Beyond that of course knock and detonation occur. I did carry race gas with me when I competed in Ohio for an event this past summer because I wasn't sure if that area had 93 octane. I was prepared to mix.
