Why would you need a boost gauge for nitrous? Would it work or woul it just bounce back and forth everytime you rev it it goes to 0?Sh0gunMX said:Well have you done mods to your engine? Usually people match what guages they buy to what they have done to their motor. For example somone running nos would fill the 3 pod with nitrous,boost and air fuel but if your just getting it for looks I think they best 3rd one would be exhaust temp. And get cobalt blue's by autometer they are nice thats what I have.
