I am running the 4600 with a 13t pinion. I tried the 14t at first but discovered it was too much for my track. I am running it with the MMP with 0 timing, no punch control, and low start power. No problems here hooking up, you just gotta know how much throttle to apply on what parts of the track and adjust for more or less traction. What pinion are you running?
According to the gear calculator, If I were running the 4000 I would run a 15t pinion.
