Opinions?
2003 F-250 CCSB 7.3L with 252K. I purchased this truck about 4 years ago and have since put Adrenaline HPOP (2 Yrs ago, LPOP (Last Month), OEM IPR when HPOP done, OEM ICP Yesterday. About 2 months ago i started getting the p1211 code. This only happens if i'm in OD and give it throttle to pass a car w/o towing or pull a hill while towing about 8500 and keep it O/D. If i do a full take off to test the pressures they are fine until i get to about 3rd gear and the icp drops to 1500-1700 psi and ipr climbs to about 85-95% causing the P1211. I tested the fuel pressure to day after filter. idle is 55 PSI and at full throttle it only drops to about 46 PSI. I believe the only other options are IPR, HPOP, or Injector O-rings. I have the IPR i took off 2 years ago and put new o-rings on it to save as a just in case IPR. I plan on swapping those out to see if that solves the issue. Forscan snap shot attached. What are the opinions of the forum?

Fuel pressure is a little low, but not sure it would drop icp anywhere near that much.
How does it feel? Does it feel like it lost power? Have you had gradual symptoms or did this just come on one day?
Possibly start w/ a Cody test, would determine if the orings are leaking.
Then can deadhead the pump. Would know which direction to go in.

what injectors and tune are you running?
that fuel pulse width is a bit high at 4.5 ms. The hpop is not going to keep up with that. Recommend running a cooler tune that does not exceed 3.5 to 3.8 ms if running stock injectors.

Does feel like it has lost power pulling Camper. Normal driving is just that normal no problems.
The tunes are GearHead. I have some tunes I Just received from Andrew but haven’t loaded them yet.
I should also add that it only does this with normal temp oil. EOT 180-200 degrees.
with Colder oil i haven’t had the problem.

Have you changed the fuel filter anytime recently? How did it look? If it was really black it may lean you toward injector orings. Does it do this every tune? Any differences between tow/race/economy/stock?
As noted above, a little more testing will help drive you to a cause.

@OP What kind of oil are you running?
It is interesting that the ICP spikes after you get off the throttle and IPR DC drops. Did you replace the IPR when you installed the Adrenaline?

Too many of those and the vehicle will burn to the ground when a high pressure oil line bursts sending 3500+ PSI oil mist straight at the 1200+ degree turbine housing after a hard pull.

Pressure is not shown through Forscan. I stated it in initial post. The pressure spikes of icp when I let off throttle is I'm assuming because the valve is closing off which causes a momentary spike. Could be wrong.
Shell T6 15w-40 oil.
yes IPR replaced with OEM at time of HPOP
edit:cleatus beat be to it.

When I bought my truck, it did the same, all stock. Was both the orings and the hpop. Each improved it some. I know you've replaced them already but something isn't right now and suggest the tests I mentioned above.

Guess I should also mention that Truck starts great but recently when hot it turns over ALOT more before it will start.
still haven’t had a chance for the Stock tune graph. Work calls….
