Nope, there's too many variables at this point. On something boosted, it's best to have something watching the airflow. The MAF is the main input for most of the ECU's calculations, so boosting it and running it Alpha N (where it'll be forced to estimate the airflow) could easily end up with a melted engine.
ACS should have had it well tested before releasing, and it should be spot on. They'll have had access to full engine dynos and loggers and it should be calibrated very well.
