I'm asking these questions trying to decide if I want to put a Bully Dog Chip on mine. I don't want todo anything to damage thing worse if the hiss is a problem
the chip should have no bad implications to your truck as far as the hiss. the hiss will still be there. the only way to get rid of it is to disconnect the valve or gut the valve all together, but the chip will not affect the hiss positivly or negativly....
