I did this once not too long after I started getting into racing my GN(about 45 seconds after I bought it).I can't remember how high I took it,boost wise,but when I pulled the release,the pedal came back so hard that it bent the E-brake stops,and broke the trigger for the idiot light. The brake light has been on ever since as a reminder to my stupidity. It was one hell of a burnout,though!
