Power Loss - 3 Different Codes

Did some searching within the forum, and I found people with the same codes, but not the same 3.

2003 6.0, 160,000 Miles.

Yesterday I went for a drive and about 10-15 minutes in, I started up a large hill. When I got to around 40mph, and the truck started to shudder bad and I had no power. Turned around, came home, grabbed another vehicle and left it until today. Figured it was an injector issue, since the shudder and power loss. Ran a diagnostic with my SCT, and found no issues with misfires or injector pressures, but when I took it for a drive, I still had no power. I checked the codes and found a P006A - Mass or Volume airflow correlation, P132B - Turbo Boost Control A Performance, and P2623 - ICP Regulator Circuit. Not sure how these codes correlate or what I should be looking at first.

My truck does sit, but no more than 7 days at a time. I usually drive it 2-3 times a week on average, but I drive my work truck when I commute to and from work.

Any info is appreciated.

Thanks Senix

Anyone with any ideas? I should also point out with the P2623 code, I don't have
Any of the stalling, hard start issues that I've read about. The truck will take longer to start sometimes than others, but it's been like that since I've got it.

How did it drive home after the shudder and power loss? Were you making any boost?

It seemed to drive fine after that. There was another hill coming back and it boosted fine and I had no issues passing. Is it a possible glitch?

I'm no expert, but I've had a MAF fault code on a turbocharged car before. The intake tube came loose between the MAF sensor and the turbo inlet. Clamping that up solved the issue and cleared the code. As for your other codes, I can't really help you there... But maybe the boost one is related to the MAF one.

I may try clearing my DTC codes as well, and see if they come back. Just wanted to be sure first.
