*UPDATE: Hooked up fuel pressure gauge* Runing lean at top of RPM before shifting

I can't open your HPT or HPL attachments either. I plumbed my Schrader valve into my no longer used EGR harness so I could monitor fuel pressure through the scanner. I verified my fuel pressure was dropping, and then noticed my voltage was dropping at high RPM. I was over driving my alternator shaft to a RPM that was too high. I rebuilt the alternator and switched to a slightly larger OD alternator pulley and that cured my woes.
If you haven't already, log the equivalent of HPT's "Control module voltage" PID in Torque ("Voltage(Control Module)[42]" is how it shows up for me) and see what it's doing in that RPM range.
