Hello Randy,Massey will be fixing the horsepower on the XP.My brother is a dealer and he told me of this stupid problem back in November.He was told by the service rep that the problem would be rectified.With all the problems caused by Cummins I wish they would switch to a differant engine,a Cat or a Valmet or even a Mercedes like the 8460,that was a beautiful engine.I think that Cummins is overated.
