6.0 low boost help please

[jetjock15]

my 06 6.0L went towing my fifthwheel, sounded like it made a leaking air sound, i slowed down and then when giving it a little more gas the boost was only going up into the 10-15p range, where as in before that would be 20-30 psi range, i pulled over, checked hoses for leaks and tightened the clamps, could find no leak, i reved it up in nuetral a bit and it wasnt making really any untill like 2.5k where it would just make 5psi, i think usually in park when you rev it up it goes up more? anyway i unhooked trailer, and drove just around block and seemed to be normal, im very worried as we know 6.0s can have turbo issues. i seemed to be working ok, but something noticable did happen, what to do? advice? i have ID tow tune and gauges so im getting accurate boost numbers, the stock and autometer gauge both show same thing

I cant really suggest anything other then cheeking all the boots and gaskets! Sorry, I know thats not much help!

in park or neutral doing a run up there wont be much boost at all, so seeing 5 psi is about all you will see in P or N. Its sounds to me like the turbo or egr may have stuck on you briefly, most times the turbo just needs to be cleaned and likley wont need any parts.
