i have a 2019 challenger rt with the 8-speed auto and need help with my trans tune. I can't seem to get it to shift when I want during a wot pull in 1st going into second. I have had others look at my tune and it has helped, but I'm running out of ideas what it could be other than a mechanical fault with the transmission. any help will be appreciated
here is my tune files for anyone interested in helping or just wants to add to their collection
