Low power/ turbo farts/ p0238

Hello I hope someone can help. A little history on my truck 2004 f250 late 2003 build. Recent hpop, turbo cleaned, egr cooler, oil cooler, and three injectors. I had a p0478 before one day I decided to check the map sensor tube to see if it was plugged. I took the bracket off the blower motor took the tube completely off cleaned it and the intake side looked in the sensor and everything looked fine. Put it all back together fire it up and went on a drive came home and had a p0238. Also I forgot from the time we put the turbo back on after the hpop oil and egr cooler replacement the turbo will fart at 1800-2100 rpm. Also when yo let off the throttle it will fart. The problem is still there p0238 lack of power and turbo farts. Has anyone had a similar problem??? I'm don't have a scanner capable of reading the map psi.

You also need to check the EBP sensor and tube (Exhaust Back Pressure). Its bolted to the thermostat housing, just try unplugging it first and see what that does for you. If no change then im going to say egr valve is plugged up. Im assuming you have one since you said you replaced egr cooler. Good luck

Sounds like the vanes on turbo still sticking. Small amounts of rust build up can be a problem. I bet if you ease in and out of boost you dont have this issue. Only when you goose it a little then let off quickly/or quicker do you notice the problem.

Really sounds like the same issue i had with my turbo. But i will say that i had power issues when my IPR screen failed.

Could be looking at a little of both.
