    Made 2 pulls today after work. first one was 12mph roll to 115ish MPH, second pull from a dig. Tune set to shift at 6500rpm (110mph on 3-4 shift). Shifted perfect, and didnt miss a beat. I made and uploaded this tune on the latest version of 2.25. I have a video if anyone needs to see it, but no log. I can upload tune if anyone wants as well

    so the fix was to find a version of your tune that wasn't corrupted?

    I never had the issue. Was just testing to see if it was a G8/6l80/2.24 issue.

    Some cars I don't even know have an issue. I mainly run the cars at the drag strip which all do fine. The only way I have found the issue is trying to make a WOT pull from 70mph using manual mode starting in third.

    So apparently I either don't have a corrupted file or it's not in the software. Made four pulls today all from 70mph or below in 3rd and 4th gears manual mode/tutd and no shifting issues at all.....
