1: I have the dyno sheets to prove it.

3: Just because say 32 deg timing works best for peak power (at say 6700rpm) it doesn't mean it's best at 5000rpm or at 7200rpm. If you've ever monitored timing with a scan tool on a modern efi car you'll see that the timing is very dynamic. Even above 4000 rpms. The manufacturer does it for economy and emissions but it can be tuned the same way for power.
4:A year ago I would have said the same thing. but after 9 megasquirt installs and hours of tuning them on the dyno I know differently.
