8.3 cummins

Hey I am a full time mechanic for the army guard and I have a 936 A2 wrecker (for those in the army) and for those not it is a 5 ton 6x6 with a 8.3 cummins in it and I have big problems 60mph down hill lucky 30mph at the top unloaded even worse loaded (this is a wrecker so it is draging something all the time) and I have been in the exact same style truck and it had no problem making it. This truck has a new motor ( someone blew a coolant hose and did not stop) so I know it is not the motor it does have a tiny fuel filter on it I and about to bypass it to see if it is to restrictive but I was wondering how to adjust the injector pump? It has a very similar pump to the later 12 valve but minis the electric stuff. My higher level maint told me that it was the torque converter I don't see how because you put it to the floor from a stop and it will take about 15 sec to get it to get to 1800 rpms we had to low lock it to day going up a hill in town because it powered out unloaded #@$%! so I am just looking for some ideas to fix it anything.
