Okay so when i start the truck it romps pretty hard for a second then just runs bad. My mpg is around 10.

Thruck is a 2000 7.3 with 38r, stage 2 180cc injectors, SRP1 pump, beans tuner, regulated fuel return, automatic tranny.

Did contribution test and it came back with number 8 cylinder fault. Idle hpo was 600psi at idle sometimes dropping to 590psi. IPR duty cycle was just under 12%. injector width was 1.45ish. When the truck stumbles is when the number drop a little.
Are these numbers good? What else should i check?

Replaced icp lat week and truck actually ran better but still lacks power and has bad idle.
