    I believe I read somewhere (turbobricks?) that the factory boost guage is highly unreliable. They recommended the installation of an accurate boost gauge.

    well I was running 17 psi and on a 700 I think half way is about 7 or so and gauge tops off about 14 I seen on a site somewhere that had the numbered gauge to fit in the factory dash location with boost up to I think 20 psi nice.
