Turbo 3.1L lack of power

[WizardBlack]

You clearly have some bits that can flow better up top and some bits that are out of breath by the time the turbo spools. It seems like a lot of stock head/manifold turbo cars I've seen; just a bit bigger turbo costing you some spool, perhaps.

One observation; your timing looks too high at idle. Just as timing typically picks up a few degrees after peak torque, so too, does timing drop low as you get below 2krpm or so. The engine is moving so slowly; you don't need that much timing. Look at the point 2750rpm/105kpa. Note how it tapers more retarded as you go down on the map (higher boost); mirror that to it's left as well.
