OP-Looks like JIM5.0 explained this a little further and due to the 3V not having TiVCT like the 11+ cars there's not much that Bama can do to make it sound thicker without sacrificing idle quality and drivability. Being said there is a tweak that Bama does within their tunes for 05-10 GT's with cams that most other companies don't which will give the car a little healthier lope. PM me your order number and I'm happy to have the Bama team look into it and make sure you're getting the best idle sound out there!
