New L9 in an M2

I’ve also had mine tuned by one of our member and it woke it up. I have the Allison 3000rds six speed auto in mine. After I adjusted the parameters on the Allison software, it shifts under a load between 1950-2100rpms, same if I stomp it. If I just put put around, it shifts around 1600rpms. I also enabled the secondary mode feature and when I enable that, it shifts only between 1950-2100 rpm’s at all times. I can have a tractor hooked to the back of that wrecker and be overloaded and still pull it between 80-90mph all day
