I had a MBC but either someone playing a stupid joke on me took the adjustable bolt out (through my hood scoop while my car was parked), or it popped off while I was driving. Either way...Im back to 4psi and its not as fun as 7psi... Anyone got one laying around or know of where I can get one? There's tons of em on ebay...some cheapies for like $10 too, will those work good? thanks.
