So my tune is working really well. Just cannot for the life of me get it to shift the way it should under very light throttle on the 2-3 and 5-6. If I take off and keep constant or heavier throttle, shifts nice and firm, like I want. If I accelerate and then let off or change the throttle percentage, it will almost slip into 3rd or 6th, but not all the time. temp doesnt matter. Doesnt matter if its on E85 or 93 either. Im assuming it is a command issue, or torque. Can post tune if needed. Anyone dealt with this? Other than that, truck screams.
