Couple updates that ultimately equate to a flip flop on turbo selection - I've sold the S280 and airtec manifold.
On order and due to arrive next week I have a WOR modified stock manifold to get rid of the Vband adapter solution in the ATP kit and am sticking with the 2860. Will have the manifold ceramic coated once it arrives, then all back together.
Maybe I'll install my Maxton splitter that's been sitting in the basement while I wait. Car is currently sitting in the garage with no mani, turbo, etc. installed and the battery tender keeping it juiced. Bummed to not get to drive it for what'll equate to ~a month overall but will be worth it.
