yes. timing will cause it. if they just stuck the new pump on and just lined up the static lines, it will run, but not to full potential. needs to be propperly timed with a meter.

Glad you posted this. Except, mine is mainly with it loaded. Just don't seem to have any power with my horse, or hay trailer behind it. Of course, these are goodsized hills in SWMO. I realize my 6.9 ain't a monster motor. But, I'm gettin flipped off by grannys in geos. Wonderin if cuttin down the exhaust will help. I've got dual 3" run to glasspacks and cutoff there. Exhaust guy and mech at work said exhaust might need to be restricted some to bring torque back up. Still learning these motors, so your post helps.
