Bigdogtrucker Posted February 19, 2013 Share Posted February 19, 2013 Good friend has an "03(pretty sure)RD tri axle dump with a 460/18 speed.He ordered it new,and it had under 200K.Last year sometime he parked it for the day running perfect,next day it had NO power.Been the same ever since,in and out of Mack and they can't figure it out!Turbo builds boost,it starts right up and seems like it runs fine.It's just gutless as can be!Any idea's what he can do???

staxx Posted February 23, 2013 Share Posted February 23, 2013 Could be a few things compressor discharge temp sensor if you have one , boost sensor, intake temp sensor, throttle pedal calibration could be off and of course need to make sure you have good fuel psi.
