Down on power after IDM Change

2000 F-250 was running rough so I changed both UVCH but no help. So I took it to a shop to have the codes read and was told the Injector Drive Module was bad. The shop changed the part and the truck runs smooth now, but it is down on power. Feels almost like I have no boost? What could have caused this?

Update: So I drove the truck around a little bit tonight so I could get a detailed description of the symptoms. This thing couldn't spin the tires in a car wash! I was literally putting the pedal on the floor and getting no black smoke out of the exhaust pipe, very casual - lazy acceleration. I've got to pull a loaded trailer tomorrow afternoon and I don't think this pig can do it.

The initial issue seams to have been fixed by the IDM change. Could the new IDM cause this issue? Maybe a bad part out of stock?
