Timing affects cylinder pressure. The more advanced the timing the earlier the pressure peaks and if the piston is still coming up the pressure will be much higher than with later timing which puts peak pressure right after TDC when the piston is going down which is where you want it for max power. So you can have lower cylinder pressure and make more power. Twin plug it and retard the timing, problem solved.
