    Boost pressure sensor ?

    Maybe this has been covered in the past but where the heck is the boost pressure sensor on our Ultra 250x's ?

    How dose the gauge know what pressure to display

    I have looked and can not find a pressure sensor so I am guessing the computer just "guesses" what the pressure should be relative to the engines RPM's

    I am tempted to get the Boost gauge set up form R&D

    I did my boost gauge the other day, I decided i like using the glovebox to toss shit in it, so i mounted mine right by the OEM dash pod.

    It sit on a angled base, and i turned the guage so 10lbs boost sits at top. With bars down, which is how i normally ride, i can see it fine.
