This^. With the c/l at 80% you would never notice a difference. Set it at 60% and give it a try. I think you'll be surprised.
I had good luck with my 1700kv by selecting timing profile #2 and gearing down a tooth. You might try that too, theory being lower mechanical load and recovering top speed with a touch of timing. Remember, 4-pole motors have a much more limited timing window that 2-pole motors do.
