I am getting ready to run in the Motorcity Gumball in Sep and the Fireball Run next year. I want to install a nitrous set up in my M3. Have any of you done it and if so, what were the results and reliablity?www.facebook.com/pages/2012-MotorCity-Gumball-Rally-69-Team-SSFers/166327220133399 www.facebook.com/pages/2012-MotorCity-Gumball-Rally-69-Team-SSFers/166327220133399
