overbuilt 1.6 needs reality check
 

I've been trying to search for 1.6 B6ZE dyno graphs that'll help me get a realistic idea of what I should be expecting. My car is used primarily for drifting and street driving. The engine previously made 385HP and 290TQ on E54, but this refresh is updating a lot of outdated parts, or adding more upgrades.
Do we have anything to compare a build like this to?

This was the original tune. 407HP & 331TQ @30psi on E85 with 8.5:1 pistons.

A new engine was built and made 385HP & 290TQ @23PSI on E54 with 10.6:1 pistons.

Both were tuned by UMS tuning in Tempe, Arizona on a Dynapack.

These are the new parts that are being installed and what the parts were with the 385HP tune.
