Recently (as of yesterday) I've been hearing a sound when I get on boost. I had a friend take a video for clarity's purpose. I'm taking it back to the dealer on Tuesday to have them look at the rattle, but if it's something you guys are familiar with, maybe you could let me know what's wrong? Thanks.

Can't really tell. If you have any mods? If so you may want them to remove them prior to going to the dealer.

 

I think I may have figured out what it could be. I ordered AMS under-the-hood bushings; the 2010 USDM ones, but I have a 2011 GSR. There's probably too much play in the retaining clip(s) and the shifter cable(s). I'm going to go back to stock tonight and test it out.
