Set Torque/Feel at about a 3 or 4, five really only generates more heat, and in order to get more boost into the motor you will have to gear DOWN, not up, to get more boost as the LRP boost is RPM based, more RPM means more boost. I have run nearly this exact combination of ESC settings and spec motor, and it can run hard and pull RPM a long way, but it's not intuitive as saying 'gearing up gives you more heat and top end speed'.
