How does it idle in the vp44 hot wire mode after warmed up and in gear and out of gear? By those pictures I would say someone really wanted to cram that engine in a F250. Definitely custom.

Hello Guys, skipping and buck is fixed, it was a loose connection on the back of the VP44. I'm running stock injectors now. With hot wire test no hunting at idle when warm, runs nice...obvio
Hello Guys
I have a 5.9 24 valve cummins in my F250.
Im experiencing hunting at idle when in gear, worse when warm.Ive done the hot wire test and taking the ECM out of the equation and runs fine with no hunting, that said as expected no.
I made up jumper wires from the VP44 disconnecting data link from the ECM and runs smooth but only 1000rpm....since doing the test Ive emphasized the problem, now I have skipping and bucking but no hunting up through the throttle range.Can only get fault codes from PCM not ECM ?...Im on the fence on whitch way to go APPS, VP44 or dirty signal from ECM....any help would be much appreciated..Im on the west of Australia
Here are the fault codes I'm getting from PCM
