Currently our only location is in the San Diego area, with more shops opening in the western U.S. over the next couple years (I myself am moving to Portland and will be opening a shop there early next year). If you can find another 3rd party shop that is willing to install the delete manifold (or you want to DIY), we will be selling them as standalone parts.
As far as the rotor encoder sensor check, most service centers won't do this, but you may be get lucky if you "know a guy" who works at a service center. I would recommend either checking it yourself, or having a 3rd party shop check it. If coolant is present, then you may want to start pressuring the service center about it... Under warranty though, most likely they won't do anything until the drive unit starts to fail.
