warm engine miss

[cumminspowr]

I took out the 200hp injectors and put 100hp injectors in and have had a miss once the engine warms up, when the engine is cold it runs smooth. Injectors have been pop tested and I reinstalled them just to make sure I didn't miss anything. I haven't changed the fuel filter that goes from the tank to the FASS(without filters) but I changed the stock one when I did the injectors. I don't know what the fuel psi is cause the sending unit took a dump, so I have a mechanical one on the way.

Any ideas?
