well a boost controller is wut it is...controls teh boost...theres a manual boost controller and electronic boost controller..manual...u press a button or flip a switch and it switches to a preset amount of boost...for example if youre running 8psi...u flip the switch now itll let you run 12psi...i think it regulates either the wastegate or the blowoff valve...someone check me on that....but electronic is the same...except you preset it at when u want to up the boost...like say u want to up it at 4000rpms...so once u hit 4000rpms it lets more boost in...u can do it at a certain speed too
