High EGT's low boost
I need your help guys, last night when I came home the truck was running great. I was getting 22lbs boost and had low egt's. this morning when I left for work my stacks sounded weird kinda muffled not the normal grumble. Well I am only getting up to 12lbs max right now and my egt's are through the roof about 600 higher than usual. Anyone know what could be the problem?

Sounds like you have a boost leak somewhere Deven. I ran into the same thing coming back from TN
Here is the thread that I started back then

Yes, and listen to the exhaust. If it sounds like a jet, it's closed or partially closed. Could be physically stuck. Now that it's gotten cold, if the thing hasn't closed in a while, it could get jammed up a bit.

Update, started it for work today and drove about half a mile and didn't get any boost at all. put it in park and pushed the throttle to the floor and it would only go up to 1900 rpm but the egts went up to about 1000. The exhaust sounded really weird too kinda a whooshing sound so I am thinking stuck ebpv. I have had the turbo off several times but can I unstuck it without pulling the turbo. And what is the best way of doing so, should I spray some lube on it or no. Thanks brotherhood.

Disconnect the rod from the actuator and see if how the valve feels Deven. Do you feel a loss of power also?

Yeah I def have a loss of power. I got it to build boost some now. I got up to about 14 lbs but still sounds like a jet. I unplugged the ebpv sensor but it is still doing it so I am thinking it is partially stuck. But speaking of jets I have to go recover one really quick I will let you guys know what happens.

It is the one on the turbo pedestal. It is called an EPR (exh press regulator) solenoid.

Ok thanks also if I disconnect the rod is it the lower one? It isn't the one for the wastegate if I remember correctly but maybe i'm wrong it has been so long since I have worked on the turbo. also if i disconnect that actuator can I just let it dangle around or do I need to wire it?

Its the rod that does from the pedistal to the exhaust side of your turbo.. You should be able to manually move it back and forth even while is connected.. It sounds like it stuck to me too.

Found the problem guys. The ebpv rod isn't even connected my little clip must have fallen off. I haven't fixed it yet just saw it first thing this morning and had to go to work. My question now is if I wire it open, which way is open and just to make sure I am wiring the right thing I am wiring the tab on the actual ebpv right? Thanks again brotherhood.
