My money goes to something in the HPOP system. ICP sensor?

I have somewhat of the same problem. Runs rough when warming up but fine at operating temp. I've changed filters/oil, injector o-rings a few months ago but i am also leaning to something on the HPOP side or CPS.

Have either of you monitored live data during the problem?
