Finally had some time to myself and did some measuring for you. I bench tested the 1400kv Tekin motor with the MMpro on 4s. Seeing the data I believe you can pull of the 6s with Cheat enable.
I used my Rustler with 58/25 gearing with the wheels suspended. I can only see the rpm in live mode and for some reason can't get the rpm readings to save.

4s Regular 10 degrees timing was a bit more than 22000 rpm.
4s CHEAT 30 degrees timing was a bit more than 33000 rpm.
Cheat 50 degrees timing on 2s was a bit more than 33000rpm. This was pulling 70+ amps and got hot really fast.

So I looks like I went from 1400kv to 2000kv with 30 degrees timing. Pretty cool.
