Problem With Spooling

[RadarRider]

The other day my truck was running fine. It was taking off no problem, had plenty of thrust, & when you stomped on it, it took off like a bat out of hell. Now yesterday, I took it to work & I'm not getting any power! I can hear the turbo spooling, but's it's not making that high-pitched whistle it normally makes. My boost guage isn't reading anything @ all. The funny thing is: the engine is running fine, there are no funny noises coming from the turbo or the engine, no exhaust leaks, & no SES light from the truck or ALERT from the Six-Gun. Today, I pulled the intake sleeve off the turbo to check the compressor wheel. It didn't appear to have any damage, I can still spin it with my finger, & when I'm spinning it, it's not making contact with the compressor housing. What the F?!?! My turbo's no longer giving me love! Can anyone help?

Does the turbo spin when the engine is running? Is it a 6.0 or 7.3?

Under acceleration it does. It just doesn't reach full potential. It's a 7.3, by the way. If it helps, it's modified with: Banks Compressor wheel, Big Head wastegate acutator, & Power Elbow. The wheel doesn't appear to be damaged, & like I've said; you can hear the turbo spooling, but doesn't seem to reach full boost.

Well, I found the problem. The "T" for my boost line was broken. I just can't believe that little piece of plastic was causing severe power loss! Anyway, I went to the parts store & scooped another T of the higher quality variety. Popped 'er in & I'm back to driving sideways because it's raining today!
