Key to getting ITB engine running perfectly is to have at least MAP compensation table+MAT compensation table on top of Alpha-N or the best method is to have MAP/Alpha-N hybrid load.

Check out the AEM Infinity ECU. You can set it up to use throttle for load, MAP for fueling and Baro/altitude and it works REALLY WELL on the street.

A buddy of mine just finished his install and the car runs just as good with ITBs with throttle based load as it did using MAP only and a regular intake on a Ford Coyote.

My car is currently running throttle based load and MAP based fueling and it runs great on the street.
