I don't know of any modifications to the new motors to increase horsepower like you could on older carb models. I'd be real hesitant to mess with an Etec as they are solid the way they are and direct injected.
About the best you can do is prop it correctly, then consider a jack plate if you believe your transom can handle it and the motor.
Personally, I think you are doing quite well getting 42 or so out of it...might get to 44 with some tweaks, and much of that is dependent on how much you want to spend to get those couple extra mph.
