"Quicker" advance curve; any benefit?

All in by 2200 and TC stall at 2600? Timing all in any earlier does not make sense to me....???

Your altitude is lowering your effective DCR by a full point; no wonder it is detonation resistant! So there is the torque issue; it's cylinder pressures are lower than a stock 225 /6 at sea level. (And combustion temps are low too.) One you get to that high elevation, the sea level build thinking goes out the window.
