    It probably will bring that back. If you've got stalling issues, then you need to add air to the Desired Airflow table.

    No, I wasn't looking for that... I was looking for what's causing your cruise control issue.

    I did the RAFIG and RAFPN both using DYNAIR (since I am SD) and they are both dialed perfectly with this method, so I will zero that table and give it a shot. The trims bouncing so much is causing a slight surging problem. I can feel it and everytime I feel it I can see the trims changing.

    So you don't think timing or torque converter would have any effect on cruise control feeling?

    RAFIG/RAFPN is not a perfect method... it can give wrong values, particularly with cammed engines.

    Yeah, I was following Shawn's post where he used the MAF(or in my case the DYNAIR) vs. ECT instead of the trims to dial it in. I thought that method was much closer. It runs well, just the cruise issue and slight surge.

    So you saying even Shawn's method can give wrong values too? I read that using the trims would give too low of values.
