So I just bought the gauge. and hooked it up... just wondering how accurate it is. reads hp? but is that at crank hp? or what how does it actually read it? and boost... i know thats wrong. at idle says i'm at 9psi. knockretard is at a steady 0.0 but do i need anything else set up to read that?
any help would be great... thanks
