the previous owner of my mini put a 17% pulley on the supercharger of my mini. Now the computer has figured out that it's not programmed correctly for the after market pulley that is on the supercharger and my car goes into safe mode whenever the boost kicks in. The shop who has my car is telling me they can't program the car to recognize the after market pulley and I should put a stock pulley back on the supercharger but we can't find a stock pulley anywhere. How can we get the computer to program correctly for the 17% pulley that's on the supercharger now or where can we get a stock pulley to put back on the supercharger??? I haven't had my car for a month now and I NEED this issue to be fixed!!! Please help!!!
