6.0 low power

The other day I pulled a pickup out of the muck. I had it in high range 4x4. The turbo spooled up like I've never heard and I jerked him out of the mud. I unlocked the hubs and headed out. I didn't really notice anything until I went to pass a truck the other day and it seemed to be lacking power. The boost gauge doesn't climb as it did as usual. Today I again tried to pass and it felt like low power once again. So I did a hammer test and besides the low boost, full throttle made my EGT's jump into the red . Now I'm thinking stuck turbo but could it be something like a blown hose still partially connected? I'm no mechanic. Plan to have it looked at next Tues.

EDIT- I plan to drive it, any reason not to on flat ground? Been on the road daily and with normal driving the EGT's stay in the green zone.

Thanks for any suggestions.

I would definitely check the intercooler plumbing and boots. Do you hear a whistle when boosting?

Turbo could be sticking but my guess is a blown CAC boot or crack. Also, inspect the MAP sensor hose. Any codes?

Nope, no codes. I never even looked at the boost when I pulled that guy out but it was more throttle than I've ever applied since adding the tune. Stupid not just using the winch or just shifting to low range

Yup, my first thought was an air leak between the turbo and the engine. Check all your hoses and clamps, or make up something like this. All you need to do is apply compressed air on the intake side of the turbo.

If you're not blowing black smoke every time you get on the throttle then the leak (if it's an air leak) is after the turbo and not before... at least that is what happened to me. During a cold spell last year I blew my in take hose off before the turbo and it was if I was rolling coal. I figured out what was going on pretty quick do to the loud pop that happened and then low power. Opened the hood and did a hose inspection and found it in a couple of minutes. There are other things that can cause low power but I'd check hoses first.

Thanks. I'll have them look at that. If I open the hood and look I'll just slam it shut. Crap I have a hard enough time seeing the belt. I have done a alternator swap and had a lot of that stuff off but I'll just pay to have it done this go around.

Does CA look for a CAT (or maybe just a large tube that looks like a CAT)?
