Has all this datalogging been done solely on the dyno or have you checked them on the street? I'm curious the temp difference with mother nature helping you instead of a fan in front? I don't recall what my IAT's were at when we did mine, but they didn't ever get to a point that we worried about it. Its making 827rwhp@20psi. I also removed as much of the inner front bumper I could to maximize airflow.
