I can tell you from experience it's the VTA BOV. Mine is a b**** to drive especially when it's cold out. Runs crazy rich and bogs a lot. I don't have the old BPV or I'd slap it back on in a second. Or find a way to recirculate the BOV I have. I'm going to probably go with MS when I have the time...
Congrats on the new MSP. I too just bought mine. also Titanium Gray, and I love it. Although mine didn't avoid the BOOM with the previous owner. So I got mine with 2400 miles on it. LOL!
