Well I got coolant in my ebp sensor when putting some in my truck. This was right after I did an oil cooler. Truck threw a exhaust pressure sensor a circuit code. Replaced the sensor and the pigtail. Cleared the codes, truck is still running on low boost and power. Smokes like a freight train and won’t build over 12 lbs of boost and it takes a min to get there. Anyone have any ideas?
Does the code come back? If I understand correctly, this is as you were re-filling after an oil cooler job. That job requires the turbo removal, of course, which pretty much opens up all the usual suspects for low boost - EBP, MAP, turbo connections, CAC system leaks, air filter clog, as well as your harness wiring. I just finished going through the same thing after the oil cooler swap - it's almost certainly one of those things. Have you felt around the back of the engine for air leaks from the y-pipes and EGR connections? Plastic CAC pipe cracked? Boots all on firm.
12psi of boost is kinda more than I've seen when I lose my turbo. It struggles to get 5psi. IDK, but that suggest something that is partially working, or partially not working. Like a airway partially clogged, leaking, or fuel without enough pressure, or a FICM connector not all the way in.

I actually did not take the turbo out when I did my oil cooler. So I believe the turbo y pipes would not be the problem. The truck cannot leak from the egr… all boots are tight. All my pipes are upgraded aluminum so no cracks. I don’t see any cracks on the intercooler either. Wiring looks fine everything is hooked up. Honestly I’m stumped
Well, heck, of course, you don't have to take it out. Just all the vids show it that way, prolly allows better camera angle. I can't be much more help - all my trucks are so heavy that they just don't drive like y'all's 250/350s. When I've not had boost, it really makes a difference, none of your 12psi stuff. So, that sounds different to me, as I described, as if it might not be related to the turbo or boost at all. I assume you've driven it enough to get all the air out of the oil system.

yeah I’ve drove it around plenty. I appreciate all your input I’ll post on here what it was when I figure it out.
What code reading tool are you using?
And using non-motorcraft parts can be an issue. Especially electrical they may not read or be as sensitive as the Ford made ones.
I had a EBP sensor go bad during a vacation and grabbed one from Oreillys. Got me home, but after a few weeks it needed to be replaced.

I used both my cts3 and sct tuner to check the codes. Just to make sure they both were reading the same. I will check and see where I can get a motorcraft one from
Those tuners may only show the easy to find codes. They are not reliable for an in depth search.
Do some research and acquire the Forscan app and obd adapter. It may help in the diagnosis.
Stay clear of Amazon and eBay when looking for parts. Many counterfeits can be found there.
