Do you have electronic wastegate control? If not opening the wastegate might get you 1-2mpg. You could have a manual wastegate control cable in the cabin.
It's an a3 head on an a2 block... A3 head will give any K20a2 piston an additional .5cr due to smaller CC.

It's only @5.5psi so the easiest way to drive no boost is by light throttle. The car can be driven fast as a civic without hitting boost.
