Message double the reading using Nistune. I'm think the "Dual Intake" option for most off-the-shelf chip tunes does the same thing. I'm pretty sure this is what anyone maxing out a single MAF did prior to the Selin translator being developed.

The risk in this approach is that it assumes you're getting the same airflow through both filters. If more air is flowing through the dummy MAF than the real MAF, you'll run lean (and vice-versa). Definitely risky if you're running blind, but if you have dual widebands you should be able to check that your AFRs are what you expect.
