same thing happened to a guy who runs with me......it started changing pitch and the next day it blew and ruined his air to air also. I'd get it checked asap bro. it could be nothing but sounds to me either ur turbo or air to air is goin bad

 

Do have a fuel pressure gauge? Any check engine lights?

 

oh get your actuators checked....hope that it is just your actuators gone bad. (a lot cheaper to fix)

 

No actuators on a 01,wastegate on it though.

 

10.4 kwswan.....I did not know that, good info....thank you sir

 

I would check your pressure first, could be transfer pump, or one of the regulators in filter housing. Not saying this is your problem but cheapest item to check first. Boost sensors can go bad and not have a chck engine light also. If you have no damage to fins and no back and forth movement on turbo it is more than likely ok unless the spring is weak in wastegate. Check all that and if nothing found I would run an injector cutout and see what happens.
