So I decided to buy a forge blow off valve for my 2010 mini s. I installed the valve and made sure all connections are correct, and that all sensor are seated properly. Knowing that I installed it correctly I figured it should work fine and would have a fun drive around town. Not the case. I lost quite a bit of power, it sound like the valve is open at light acceleration, and at idle it hesitates to stay running. Does anyone have experience with this, or have any ideas?
