Not exactly sure how it would work on a f10, but the idea is to install cut out after the primary o2 sensors and before secondary ones. If you install them pre-o2 (primary) you ecu might go into limp mode. Electric cut-outs in the right spots will actually help a ton when it comes to a car with forced induction.
