    One clarification - The area where I need to make the biggest drivability improvement is during clutch engagement with a cold motor. Once the motor fully warms up, the stumble is mostly gone.

    Okay so I looked in TunerPro; give me some pointers here:
    PE Enable Min MAP is set to 15kPa - I'll look at the logs and see if I can leave this value as-is.
    PE mode Coolant temp boundary is set to 151C, so only the cold mode tables are used.
    PE enable TPS vs. RPM is set to 66% from 0-2800rpm - seems like I should drastically lower this for 0-1200rpm, and that way I can allow PE when coming off idle but not engage PE during part-throttle cruise.

    Am I on the right track?

    Anybody used both modes successfully on an LT1?
