Recalibrate it. You might not of pulled full throttle when you calibrated it so its only going as far as its been programed to go. I did this with my slash, major pain and very frustrating. When through two brand new motors to find out this was my problem.
I run this system and have no issues with the MM or MMM Everything is at 100% and the throttle is normal but my steering is reversed.
