CRT .5 is slow, need help!!!

I have the extended chassis kit from Mike, which I have to say is awesome quality and build. I am running a Mamba Max ESC and Medusa 3650-3300 V2 motor. I am stock spurred and running an 18 tooth pinion on Neu 2S 33C 5000 pack. It seems kind of slow. I am running default settings on my ESC with the punch control being set to 50%. Do I need to change my ESC settings, different pinion, change to a 3S, or a combo of things? Any help would be appreciated. I am used to running a brushless 8T aggressively and this setup is anything but aggressive for racing.
