Has the fuel pressure regulator at the secondary filter been R&R with the upgraded one like International uses? It was supposed to bump the fuel pressure up to 100 PSI in the housing, but rarely got higher than 80-85 PSI. It would always improve the 444 engine's performance. There was also a turbo wastegate that could hang open at times. I worked for an IH dealership for 11 1/2 years up until Sep. "12, and have forgotten a lot of what I learned. If I was still there, I'd be able to get their troubleshooting charts and maybe help you more! Also, has the High Pressure Oil Pump that fires the injectors been dead head tested and checked to make sure that the drive gear is getting loose on the pump shaft? Another item to check is the Injection Pressure Regulator Valve that controls the HPOP, along with making sure you have good connections on your harnesses to sensors. Any loose/intermittent connections can throw codes, cause your problems. Sorry for the long reply, but these are all thing that need to be checked. Hope this helps, I've never been a good one to fix something over the phone/internet!
