Truck is an 05 model. I've been going through every option on DashBoss, and haven't found EBP yet, might it be called something else?
@ BryanStein, I'm still trying to understand what the difference in the measurements mean, I'm not at the point to interpret them yet.

Yep you found it but as noted, it's only measures in PSI vs your MAP and BARO in hg inches.
If you do the conversion as Bullett addressed in my thread, if it's correct, showing the same as the other two measurements, it would show about 15-16 psi. Just what yours is at KOEO.

your EBP sensor is Bad or your exhaust is Blocked cant breath or V-ref
EBP was good at KOEO and Idle I cant tell you the exact conversion of Hg to PSI but Iv seen these numbers converted before and your CLOSE
EBP is Way to High Normal EBP is 16-18psi (Your 10-12psi to High @29.1psi) at 2500rpm you lost it at High Idle the truck thinks is Has Boost you also need to clean and check IAT#1 &2 @ cold soak

Blades,
I'm not sure his EBT's are bad.
With my injector(s) bad, it showed KOEO EBP at 14.3 vs his at 14.1. My idle was 17.0 vs his at 16.4 in hg's. At 2,500, mine's was at 28-31, his at at 29.1. Very similar.
If you convert hg to psi, his readings were in hg inches are 28.71, 33.39, and 59.25. Now when checking your BARO, they're at 28.1, 28.1, and 40.2. Pretty close to normal for KOEO.
Not sure exactly where you are at with elevation but I'm a couple hundred ft or so above sea level at 29.2 so we would probably see a little difference based on elevation.
Now with my injectors fixed, my EBP numbers really haven't changed so my EBP wasn't the issue. I'm not sure yours is then off.
I'm Not trying to dispute and surely Not the expert, just learning myself with issues but the comparisons above make me think he might be okay?
Please advise if I'm looking at this wrong.

All I can do is go off the Values Given (Also counting on them being taken Properly) and Fords Specs Also the value DB display said PSI maybe it is KPA IDK how DB is Programed I know if anything like SGII the Gauge could be programed wrong
If the gauge is reading in Hg then I think that value was Close enough IIRC and EBP is Not the Problem
Iv seen it go all different ways over this particular DTC
Im really counting on his BK 29.1 PSI (Its not Brake Pressure is it LOL)Its EBP right???
EP
Exhaust Pressure
KOEO =103 (15)
IDLE =110 (16)
2500rpm =110 (16)
It didn't paste right But the values are Correct or Per Ford the Ones in are (PSI) the Other is Kpa
he Had around 30 PSI @ 2500RPM IIRC Id have to go Back and reread
He also needs to check EGR Postion to make sure its in right position at this Time the value was taken it may create part the problem
PLUS he checks OK at KOEO so theres No Gurrenty the EBP will solve it slim chance its a Wire chaff creating bad Info or something edit 9but that should be continuos

Thanks Blade. It is Exhaust Back Pressure. Also, when I set up the DashBoss, it had the option for both BARO and MAP to be either PSI (which I chose) or Kpa.
I'll play with the DB some more tomorrow, see if I can find the EGR position as an option. I've been busy renovating a travel trailer I inherited, so the truck hasn't been touched yet (it's been OK around town), but I plan on working on it soon.

Pulled and cleaned the turbo, noticed a little stiction on the impeller before cleaning, now its smooth as butter. I got it back installed in the truck, an now no boost at all (dash gauge isn't moving, DashBoss is showing no more than 0.9PSI). Heading back out to check the MAP, MAF and EP sensors, and grab another set of readings (I was only looking at boost). I did try running the truck with the air intake off (so I could see the impeller spin) and with the intercooler feed off to see if I could feel any changes in pressure. Thoughts?

Final update on this one. Seat of the pants feels like I have less turbo lag (could be wishful thinking), but hooking up the travel trailer and doing a lap around town (including hills and highways) seems to have fixed the issue. I could go to full throttle for climbs, was able to set the cruise control (couldn't use it going to Idaho, as it would drop too much speed, then go to full throttle to catch up, triggering the limp home mode), and generally noticed better driveability. Overall, I'm happy.

Glad to hear you gotter fixed.
