So what I have been doing is keeping a note book with motors and their numbers, first being timing and what it actually was on the motor can, then amp draw, and RPM's along with voltage, then at the track temps, personally I would keep it under 6.5 amps, seemed that the amp draw was more than the RPM's, also making sure to keep the battery charged makes a huge difference, but I will say I am no expert on tuning, just reading and trial and error.
