Put me in the "something is still not right" crowd. Torque peak at 4600 rpm is only a little surprising, seems about 2-300 rpm high for that cam, but the HP peak also at 4800 rpm is not kosher. I'd expect a horsepower peak of 55-5800 rpm

Myself, I would still want more spring seat pressure, another 15-20 lbs there. It might not have an outright stutter anymore, but power is still hurting if it quit pulling at 4800 rpm.

The distributor has been mentioned also, that is worth a look. Needs to have a higher rpm than stock capable module, and a better then stock coil if it doesn't already. Put the digital box and Davis coil back on if you haven't already.
