No drive in two wheel or 4WD? Do you have front loader? Nothing works, no three point? All hydraulics work off the same hydraulic pump is there any water or moisture in the hydraulic oil, that may be frozen, keeping pump from getting fluid? If you loosen line on the outlet side of the pump is fluid flowing?

I have a 2006 Pete 359 with a Gefco 30k drill. Sorry my bad.
Low power from nxs c15 boost is 38 psi this engine is rated at 550. When my compressor is running the engine should be at 1850rpm. 1700 rpm is max. If I turn on headlights it drops another 25 rpm. I'm on my 3rd ecm. The only code that pops is a ghost to computer. It happens first when engine is cold. We have lower power. White smoke. Only way to clear it is to set the cruise and accelerate with the cruise. Then we get full power and code disappears. But it's still not giving me the full 550 hp. I'm not getting any help from peterbilt mechanics. There are no turbo or intercooler leaks. No bad fuel lines. We are constantly changing fuel filters The slightest restriction causes low power. The one thing that's different from this and a road truck is that it requires full hp with the driveline not turning the rear axles. So programming the computer correctly is most important. The rig drills in 7th high. Throttle is set at 1850 rpm. The compressor on the rig is my dyno. You tell me what sensors or fuel pressures to look for or change and I can do a performance test with the compressor. Thanks Driller … read more
