turbo help

you won't see it move just setting and may not it these turbo where not loud because of the exhaust being 2.5" clog cat and muffler now like rest of us exhaust is one first thing we place with 3" down pipe with 4" back that wake up the motor and turbo will whistle
now waste gate works off vacuum there is no adjustment
How do I check to see if I have wastegate problems? A quick test would be, at idle, see if the wastegate rod is pulled up into the actuator housing. If it is, that is a good start. Now, pull on the rod, and see if you are able to move it. Pulled in means there is vacuum. Suction is good, but how much? If you are able to move it, then you may not have sufficient vacuum to maintain boost.
To really test the system you should get a vacuum gauge to verify readings - with engine idling you should have 26"hg at the vacuum pump and 15"hg at the wastegate, but the above 'pull-test' will show if you're in the ball park
