    2010 SRT8 Charger not shifting at WOT

    Hello guys, Ive got a 2010 SRT8 Charger that I've been tuning on for a few months, trying to get the hang of everything. Lately I've noticed that at WOT my car does not shift UNTIL I remove my foot off of the pedal, then the car will shift into the next gear. I've recorded a data log attached below, as well as the tune.

    I've exhausted all of my ideas and I can't find anything related to my issue on the forums. One thing I've noticed while looking through the log is that my "Throttle Position" is bout ~10% higher than my "Relative Throttle Position." Not sure if this is normal or not, but regardless if anyone has any input it would be MUCH appreciated.

    Thank you!
    -Jack

    Note: The specific shift I'm talking about happens around 3 minutes in, however I cant figure out how to trim my tune as exporting it isn't working for me, LOL. The RPMs keep going up until I hit limiter (~6300) and when I release the pedal it finally shifts.

    Anyone have any ideas? Sorry for the bump. Would like to get this thing running right for the track in the upcoming weeks.

    What Rpm are you trying to shift at vs where was it shifting at before.

    Read thru this thread might help you , the other thing I looked at your tune and Log, and honestly I'm no transmission guy , I leave that to other people but .... 1st thing I'd try is Shift General>Enable Pedal , I'd drop that to 95% see if it helps,
