Good evening everyone. I have a question about EBP. I’m not sure what it should be or if mine is even correct. I have attached 2 pictures on this thread one is at an idle and the other with KOEO. I have read so many different numbers on this and I just don’t know what’s right or wrong. My truck is a 2006 F250 with the 6.0 and I am using Torque Pro to monitor everything. Any help would be great.
The only thing that sticks out to me is your voltage (Vbat) at idle is low - with the truck being run (somewhat warmed up) did you snap that right after starting? As I'd think the GPCM would have either not cycled or had a very short cycle... And here you asked about something else... What alternator set up do you have and how old are your batteries and how are all the connections?
I did snap it right after starting it. I have the single alternator and my batteries are 2 years old. The connections are all clean and tight. I am intending to get new batteries sometime this week, I pull my 30 foot race trailer with this truck and getting stuck on the side of the road is not something I want to deal with when my trailer it hooked to it. I did notice the voltage when I was posting I think I will replace the alternator also just for piece of mind.I know while I’m driving it is at 13.3 to 13.7. My biggest concern is the EBP when it gets up to 50-55 without my trailer hooked up to it.
Great, thank you very much. I didn’t know what to think because I have been seen all kinds of numbers online. I need to learn to stop trying to figure it out myself and just ask.
I would say it is on the high(ISH) side, but not unreasonable - and I have a turbo back exhaust upgrade that might result in a bit lower pressures than some.

Howdy,
I have similarly high EBP at high throttle settings when driving empty on straight and level highway......but only when the Boost is around 30psi.
My turbo VGT system is very sticky (or completely stuck now) and when it's indicating excessively high boost, I also have around 53psi EBP. I suspect that if the vanes were moving the correct commanded position, the EBP wouldn't be nearly as high (and neither would the boost be exceeding around 20-25psi)
I am removing the turbo tomorrow to clean up rust/soot to free up the VGT system . When I get it all back together, I'll report my EBP and boost at various throttle positions.
I still have the cat installed, no mods other than indicated below, no aftermarket tuning.....(and less than 50,000 miles on the truck)
Ok, got it apart, and discovered that the unison ring was literally "frozen" (rusted) in place. It would not move at all and I had to carefully pry is loose. (the unison ring is stainless, so no rust on it of course) I am pretty sure this was causing the HIGH EBP and high boost pressures (30psi)
Once loose and the cast iron surface buffed with a wire wheel, I still had to use a file to get the unison ring to move easily on it's surface.
It's now all free and I could probably put it back in the truck and it would be good for another few years.....BUT, I'm just going to replace it with a stock (new) turbocharger from KC.
I am thinking that this could be the OP's problem too.....But you won't know unless you pull the turbo and split the exhaust housing to look.
Looking forward to those numbers with the new stock turbo.
Yeah.l UPS says it'll be here on SAT. Pretty sure it'll take less time to install it than I took to remove it!
I also am replacing the oil feed line with a newer style (all steel ) line.
After cleaning and freeing up the the turbo I took off, I am wondering if I should keep it (as a spare) or just put it on the "for sale" thread.
Anyone have an idea what it would be worth to someone that wants or needs one? (49,000 total miles, new unison ring in 2018, everything all buffed up and working good etc)
I thought the rigid steel line was stock issue on the 05-07's.
You may get lucky and sell the turbo to someone who really needs it and can't pony-up for a new one. I still have my old turbo, even though the housing is so pitted where the down pipe connects there's no way around an exhaust leak. Just never know when you'll need a part. And considering the age of these trucks, and availability of parts dwindling, I've been hanging onto anything that isn't completely wasted. I guess it comes down to how much space you have for storage.

Yeah, I thought is was too. I don't know when mine was actually built. Maybe the change came in 2005.5 -- up
Mine had the flex line. I suppose it would have been ok but KC told me that the inside of the flex line becomes brittle and starts flaking off. Of course, bending it out of the way would likely further that problem so it makes sense to replace it with an all steel line.
