    Without a wide band hooked up you are going to be shooting in the dark a little bit, but yes you would want raise up the VE table a little bit I'm guessing no more than 4-5%. You should log your fuel trims at idle and various cruising speeds, see how off your fueling has become at those rpms, should give you a sense of a baseline for WOT adjustments. Engine>Airflow>VE Bank 1 and Bank 2.

    Also you should be able to add a degree or two of timing, especially down in the lower rpm range where you have decent increases in airflow. Engine>Spark>WOT Base

    I don't have a histo made for that since we cannot datalog any analogs on the 2.25 scanner. Just have to log it on your dyno and go RPM by RPM and make some adjustments.

    Not much torque management you can do either, we don't have control of the TCM yet.

    EDIT: you could use 2.24 scanner and just log rpm, commanded AFR and actual from the analog hookup.

    2.25 is only for newer dodges, jeeps, Chrysler, etc. Anything that was read with 2.24 before you will likely still use 2.24. 2.24 is still out there and supported. Sounds like you will be using both.

    no, both can be installed at the same time, you simply open and use whichever version you need for the car you are working on.
