1) The boost pressure sensor that Active/Turner refer to - do others use this too?
2) Are Active Autowerkes and Turner Motorsport are same product? Same housing? Looking at the installation instructions, they display the same images and they even show a (black) ECU with the same serial number. One is $500 more.
