Yes please let us know, I need to get mine back to the way it was. It drives me nuts, I want this to be reliable. If it is the turbo then I will replace with a good one.

Another update for you...the problem persists. Had turbo no spool, and threw a lot of codes. Took it to the dealer and checked everything, all ok. This time we unhooked the edge tuner and put the wiring back to stock. Wouldn't it be a shame if the friggin edge was the problem the whole time. I'll let you know...

I am SCT tuned. Mine is doing it stock as well. If it is would having someone elses tunes straighten it out.

Went to the dealer this morning, had the tech replace the EBP connector, checked the MAP hose for cracks, and also pulled the tube and checked the block. All ok. Also had him run the pressure values KOEO for the Baro, Map, & Ebp. Here's what it was showing:
BARO ~14
MAP ~14
EBP ~17-18
I know cheezit said they should be around a few tenths of each other...

Cheezit, the EBP sensor is brand new. Do you think I could have gotten a bad one? I will say this, those readings were this morning. This afternoon when I went back and took the Edge off, he re-ran the test and they all showed ~14. All three this time. Can the Edge have screwed up all this. It threw codes ALL day long. I unplugged the Edge and bam...no more codes for the rest of the day, and I made a 70 mile trip again. Truck runs great so far, tomorrow will be a good test. I have to tow the boat (8000#) about 50 miles so it will get put through the paces. Please Lord, let it have been the Edge...I've replaced everything else.

If there was a vehicle in my bay with THOSE readings, I would have stopped right there, and quoted the cost of an EBP sensor replacement to start with. I would then observe how the three sensors read, as soon as the engine starts and runs. Normally, MAP and EBP should increase slightly once the engine is started, while BARO should remain constant throughout all operating conditions. I would then shut the engine off, and leave the key in the RUN position to see if EBP drop to atmospheric pressure is instantaneous. Because if it isn`t, this would indicate the EBP tube is plugged with carbon and requires either cleaning or replacement. Think of it this way, the three sensors are all pressure sensors. When the engine is not running, all three sensor readings should indicate the exact same since there is no pressure change in any part of the engine. EBP pressure reading incorrectly WILL have a direct effect on turbo boost (or lack thereof).

M-Chan, good info man. The EBP is new, we also pulled the tube and checked it and the ex port for blockage, it's good for sure now. We also replaced the Ebp connector just to make sure. Since I've pulled the Edge, it's been running like a charm, and the three pressure values all went almost exactly the same. I just hope that was the problem from the start. We did notice one thing, we pulled the EGR valve while we were checking the MAP hose for cracks, and it was heavily sooted up. It is only three weeks old, and the EGR cooler and intake looked pretty dirty. The tech said it might be a good idea to replace them since we've already changed everything else. The dealership is offering to do it labor free, you think I should take them up and get the EGR cooler replaced?? thanks,

I thought so as well. Thanks for all your help guys. Truck did well towing the boat today. No codes, turbo worked great. I did spew some coolant, so I'll check with them on that Monday. Thanks again guys...

one of the reasons you keep getting a heavy soot load is from the edge. You are adding more fuel, more fuel = more soot.
ebp issue will also cause this because the pcm will command the egr valve open to reduce backpressure. causing more egr flow then really needed.
me thinks you may have an edge issue.
