loud pop

[Midwest_Mudder]

How quickly did you turn it back over after you shut it off? Also what kind of exhaust do you have? Back in highschool my buddies and I used to do what we called key drops, basically drive down a street, shut the car off, and then restart it. You get a huge "bang" from the exhaust, sounded about like a gunshot. Can't remember if the FI trucks would do it, but I'm pretty sure they did.
