limp mode!? turbo blown?! help please

[jojoampt]

Sooooo, this afternoon i went to visit some friends way out in the mountains, and like five minutes after driving (pretty spirited ) up the windy hills all of a sudden the car had no power and my boost gauge wouldnt go above 0!!

i babied it for a few minutes and then all of a sudden the turbo started working again but only for like two minutes and then back to no boost. the rest of the way to there house was boostless. but then heres the strange thing, on the way home i had sporadic boost for awhile and then it just started working again and has been ever since

i figured it couldnt be just a boost leak because then i dont think id ever get full boost, but then again i have absolutely no clue what im talking about. it was almost as if the turbo just wasnt spooling sometimes and then would kick back in every once in awhile; and now its back full time.

im super confused as to what the hell is going on, so any help would be greatly appreciated thanks in advance. HELP!!

EDIT: i just realized that in my haste, i didnt even search, so please dont flame! i realize i didnt search, but i am now

sure sounds like limp mode..

No CEL? Scan for codes regardless

2nd! Get the scan. Go from the results.

The waste gate sounds like it's stuck open/not closing, which would cause all the exhaust (or most of it anyway) to be diverted around the turbine in the turbo which means the turbo isn't going to spool. this could be that the rod from the actuator to the waste gate arm broke/disconnected, the waste gate itself could be stuck open, the actuator could be stuck open, or very possibly the N75 is not working correctly.

*N75 would be my focus after reaching in and just verify that the actuator to wast gate arm rod is tight and does not freely move back and forth.

if you popped off a hose the boost would not be coming back once and awhile.
if it was the turbo typically you would have one hell of a dentist drill or some other bad noise coming from under the hood.
