Yeah, no way to trim the data itself. Thats why I had to use a mechanical boost gauge, the ECM only reports absolute pressure and I can't find any OBD-II thing that can display as gauge pressure.

Scanguage II can display boost pressure, but it uses a constant for atmospheric pressure. It's not smart enough to read the atmospheric sensor and calculate, but you can adjust the constant to account for altitude.
