opinions / help on vv turbo

[StrRacerX]

Here is the story, on my way to the desert, I was crusing up the mountains towing my toy hauler doing 50mph and boostin around 30 psi. I heard a loud pushhing sound, like I blew off a charge pipe. The boost drop to 15-20 psi. It was all down hill from there (to my destination ).

I waited till the next morning and checked all the hoses and pipes, no cracks or pipes that came loose. Well I head home and up the hill my boost was between 10-15psi (which took a while to buid up to). Halfway home there was no boost, a big loss in power, and i could still hear the turbo spoolin.

Next day I took all the charge pipes and hoses off and clean rhem up good and reinstalled them, no difference. I think the vanes need a cleaning, but before i do that, I would like to hear suggestions
