The answer to that question is why you are data logging. Based on the limited info you provided, if does look like you are universally rich. You could try backing it off a bit and then see how your data log looks. Drop 1/2 lb and see if your 105s become 115s... Word of caution: you don’t want to ever run too lean at high loads - you can burn out your motor doing that. To really do what you are trying to do, you should have a wide band 02 sensor and chip program capabilities. Do you have a chip burner /are you going to be able to program your own ECM chips? If not, then fuel pressure may be one of the limited tools you have to make adjustments.
