I wish I could be more hep to you but im just focusing on speed runs with this car. If I were you I would buy a castle monster esc next. The toro esc is only 120amps, probably causing the ofna motor to get hot. I assume the 2650 will get hot also. Tuning is sort of a per track basis, maybe some of the local fast guys could help you out more on that. My gtp2e has been my track car for the last couple years.
