Engine sputters
I have a 2005 6.0 PSD, and on hills when in a hard pull it sounds like a gas burner misfiring. It will do this running empty or pulling a load. I can increase acceleration and make it shift to a lower gear and it solves the problem. It never has shown any kind of code, and runs and shifts very good other than this small problem. Just wondering if any one else has experienced this problem. I have talked with two different service managers and they are clueless.

Most all service managers are clueless. That is part of their training.

Have your dealer look into these:
Light Surge after Turbo Replacement:
2004-2006 engines that exhibit a light surge on light acceleration up to 50 MPH, typically after a cold start, at steady speeds between 1800-2800, or when climbing a grade (towing or not), may have a sticking Variable Geometry Turbo actuator. If diagnosis leads to replacement of the VGT actuator, the turbo lube oil line--P/N 3C3Z-9T516-BA; should be replace as well. Broadcast Message 4459.
2003-05 Various Running Problems, Check Engine Light; New EBP Sensor:
Trucks built before 1-17-05 that exhibit buck/jerk, hesitation, lack of power, stalling, stumble, black smoke, surging, rolling idle, changes in engine sound at idle or when driving at a steady speed, or with the trouble codes P2263 or P0299, may have an exhaust backpressure sensor signal that is incorrect or erratic. A revised EBP sensor is available if this is found to be the case. Part number 4C3Z-9J460-A. Broadcast Message 3815.
Normal EBP signal reading should reflect atmospheric pressure with the key on/ engine off. Typically, this is 14.7 PSI/0.88-0.9 volts at sea level, decreasing one PSI/0.10 volt for every 2000 feet of elevation. It should be within 0.5 PSI of BARO and MAP sensor pressure signals
Good luck.

My 05 was doing the same, dealer changed the EBP, didn't help, then they changed the EGR valve, didn't help then I unpluged EGR valve and all is fine so far, pull 14,000 camper about 600 miles and also smaller trailer later with no trouble. Might want to try unplugging EGR. The only thing I have noticed is fuel miliage has dropped a little.
