Iam looking to get a nitrous system, and after some looking arround and reading up on some old threats, it seems like everyone is recomending a WOT switch to activate the Nitrous. In my mind its more fun though to activate it with a button and have it spray as soon as you hit the button, not waiting for WOT. I will still have a window switch as well as a fuel pressure cut off switch. Would this be save??? And if not why is it better to have a WOT switch??
