Your a/f ratio is a bit lean and I bet you're getting detonation, hense knock retard.

Nice HP curve, but I kind of agree with the other guys on the torque curve. When I changed my stock timing table to a table that Chris Robinson did for me, I gained a bunch of area under the torque curve in the low/mid range. Check out my recent dyno sheet. Your cam should be better in the low/mid than mine since it's a tad smaller and on a wider LSA. But you're down 50 ft-lbs almost all the way up to 4000 rpm.

I'd think an aluminum flywheel would show a torque increase too, not decrease it, since you have less rotating mass.
Wierd.
