For those that have no VSS parameters in their software try this, I used this when I was running a 4500 stall back in the day, On your 1-2 shift set the mph at 5mph and your desired shift at app 5400, this made mine shift at 6400, your 3-4 shift at 9mph at desired shift at app 5600, You will have to play with these points but I finally got mine to shift where I wanted it with this method...
