Are you sick of dealing with your diverter valve and wondering if it's the cause of your boost or turbo issues? Well then, we have something for you! The In House Performance block off plate for your turbo. This will now allow you to run an external blow off valve off of your charge tube and make servicing and tuning your BOV easier. This will work on all N55 turbos, stock and aftermarket. Stay tuned: We are working on a kit that will include a charge tube with a 50mm flange for a TIAL blow off valve.
