I had a new turbo installed on my 2012 edge.  It was an aftermarket turbo that was brand new.  I noticed that after letting off on throttle I am getting quite a bit of turbo flutter noise.  I’ve just dealt with it but it is getting on my nerves and I would like to fix it.  Im guessing is a waste gate issue.  Is the waste gate opened by engine vacuum?  Any suggestions as to what to do to fix the issue.  I paid to have it installed and rather not pay $120 an hour if it is something simple I can fix my self.
 
	thanks
