Hi guys, so I had a ported VMP TVS on my last 07 Shelby. Under boost, that thing would scream! Very loud and awesome sounding. Due to budget, I purchased the VMP TVS, non-ported Gen 1 and I added a VMP 2.5 pulley. I still have the stock TB and CAI, which will be changed out in the next few weeks. Under boost, this thing is quite as a mouse? No whine? Why is that? Even my stock Eaton screamed.
