    stock boost on a F12X?

    What is the normal factory boost on a 2005 F12X? I am considering an alpha kit, and a solas prop, and am just wondering what average gains I might expect? I have gps'd mine many times, and it averages 60.4 to 60.9 in calm to ripple water on the lakes and rivers here.
