Is there another parameter I am missing?

Tyler,
Besides the IAC count v MPH, there are decay rate and delays in the calibration.
Also Constants and Tables for Throttle Follower. The LT-5 is an "unstable" motor meaning it reacts quickly to changes, which can be a good thing. However, it can react too quickly and we see the motor stalling or going into some kind of oscillation. Particularly true w modded motors. I use these parameters and others to tame these tendencies.
One that I recently have worked on is the idle SA. Lowered it. You may also want to look at what MPH you go to Closed Throttle SA. Increasing that helps also.
