peak power

With out a dyno where would you shift this cam?
The motor will spin to 5900-6000 before it seems to fall off by the butt dyno.
I'm in the process of tweaking my Governor it was at 6100 so I grabbed a heavier one and took some weight out.

Seems to shift at 5600 now drops about 1000 rpm on the shift should I grind a little more off or leave it alone?
I could pull a half a gram by changing to a nylon set screw.

If you're dropping to 4600 on a 2-3 it's time to turn up the boost. We shifted at 5700 and ran in the mid to high 130's multiple passes with the same lobes. Flash was around 5100 with a 9.5" PTC. The valve timing events on the card suck imo. Pumping losses on the ex stroke will be fairly high.

Thanks! And yes the boost is down roads are not ready for much more than 18 psi. I will leave it alone until I get some better weather.
