RPM shifting
At what RPM did it make max power?
That should be some of your guide. Maybe try 100-200 over it to start. Anywhere from 5000-5500 could be a good target too. I never see the sense in killing the engine with RPM when shaking them down. Find a nice spot to shift and run it.
2500 isn't a bad spot to leave, BUT, you may have to walk it out a bit. Dump and stab will likely result in a smoke show!

Have fun.
