In your case it is hard to know for sure since increasing the displacement from 376 to 418 cubes would add hp/tq but lowering the cr reduces power.

Lowering the cr reduces power but it allows you to run more boost given the same fuel. So if you are running 9psi now but are lowering the cr one full point. The lower cr would loose about 2% power(per 1 point cr) but you would be able to up up the boost 1-2 psi giving you an overall higher hp number. So since you are turbo'ed you should be gaining 20-30 hp per lb of boost.
