Im using the tune on here and when i change from 880 to 440 whats the best way to adjust.. Should I change the overall fuel trim?

First change the injector size and then make adjustments to the overall fuel trim, then fine tune the tables.

You have to use a wideband and measure the air fuel ratio to know what to change.
