its not the motor. its all the in the ecu. its a preset value in the ecu that wont let your rev over a certain rpm. and to get rid of this you could do a few things. re flash your ecu with a new set of values. chip it which i dont recommend unless your motors built. or change ecu's. im not totally positive on this cause im nto heavy o nelectrical and such but im pretty sure those are the deals.
