bm3 boost gauge
Hello guys
Why does my boost gauge (pre throttle) show high numbers even if i am standing still (14.5) and when on throttle shows 30+ is there a configuration that i need to change or a different gauge? |

Look at intake manifold pressure.

Because normal atmospheric pressure is 14psi. Turbo ADDS boost OVER atmospheric pressure.
So 14psi BOOST is actually 28psi TOTAL pressure. |

Just subtract 14.7 from that number at wide open throttle. On ecutek my logs show 42 psi at WOT. But in reality, it's 27.3 PSI.
