If you have black smoke and low power under load it is a issue with low boost.

I would actually urge you to get a full time electric gauge for your truck and mount it in dash. It's cheap insurance for your injectors IMHO.

I got AutoEnginuity and connected to my truck tonight.
The diagnostic trouble code scan brought up the following codes;
P0603 Internal Control Module Keep Alive Memory Error
P1000 OBD Systems Readiness Test Not Complete
P2290 Injector Control Pressure Too Low
Engine Cold Idle ICP = 745 PSI
Engine Warm Idle ICP = 637 PSI
Engine Temp = 191.2
Oil Temp = 206.3
EBP stayed around 1.1 volts
Turbo Duty Cycle was 76% at idle and would drop around 50% at 30mph
FICM = 48V
Mass Air Flow = 4.0 to 4.7 lb/min at idle
Still no power going up hill.
Does this data give anyone any ideas or have suggestions on other things to check with AE?

ICP = 671.89 PSI
ICPV = 0.92 V
ICPD = 3616.6 PSI
IPR Duty Cycle = 84.77
Speed = 31 MPH (Uphill)
RPM = 2849
I pulled the EBP sensor and tube today just for the heck of it, they both looked clean but I went ahead and cleaned them, no change with problem.

actual vs desired ICP is what you need to look into. Either a HPO leak or HPO pump looks to be the problem.
No codes though? seems like IPR would be approaching 100% to get you to the ICPD and be throwing a code for ICP out of range/too low.
what's your boost pressure when the problem starts?

Something I did notice while going back through the test data is that up to 2000 rpm the ICP pressure was much higher and just slightly lower than desired, IPR ranged between 30-45%. Once I hit 2000 RPM the ICP dropped down to the 600PSI range and IPR jumped up to 84.77% and did not change.

that's just because of pulse frequency, I imagine. Since there is a restriction or loss of flow somewhere it becomes harder to maintain pressure as the flow demand(frequency) increases. I like 78ford's suggestion to check your IPR screen. If it's clogged it may pass just enough to get desired pressure under lower RPM but not higher RPM.

I'd air test it and clean the IPR first too, but I'd bet on it being an HPOP problem also since it's only producing 670 psi.

I have ordered the IPR socket and will check the screen. I also check the ICP for oil while I'm back there.
