Yeah, it'll work.
So will *any* db2 pump off any 6.9 or 7.3 idi. The only real difference is in the calibration/fuel limit screw setting.
If you've got a turbo on that truck, get an EGT gauge and look into cranking the fuel up - you can easily add 50% more power with no other changes. The turbo models are rediculously under fueled, so they didn't compete with the Powerstroke.
