That really looks awesome!!! Great work!
Please keep in mind...if you want to see boost, you need a load on the crank. You need something to slow the crank enough to allow boost to build up in the cylinder. Otherwise, excess intake causes excess RPM. Maybe install a clutch, a chain and put the chain around something that won't move? That way, you can read your boost gauge as the clutch smokes, and you can allow it to cool at idle.
