My boost gauge is fucked up. You all caught me... I think the plastic hose is messed up a little.

Ran plated stockers for years and highly recommend some sort of solid for anything making power

So it's possible it's the gauge itself, but it's also fairly slow to react to changes. Even if this one is not 100% accurate, I'm almost certain it's not getting a great feed either.

Blow in it, I am sure you can hit 10psi. Others may break the gauge.

Final word... pistons are out .003 from the deck, and gaskets will compress to .050.  Lands compression dead nuts on 10.2 with the TFS heads.  I am psyched.  That's exactly where I wanted it.
