6500 is too low to shift.
converter guys all built them for an engine turning 7500+ by looking at the dyno sheet. your 6500 shift makes the RPM fall way below peak TQ. The converter is hanging and can't climb RPM back over peak Tq. If your going to continue to shift at 6500 you need a converter built for the power curve from peak TQ to 6500 on the dyno sheet. Your leaving power and ET on the table.
Shift it at 200 above peak HP on the dyno sheet with the converter you have and look at the ET/MPH.
You need to have a serious conversation with a good converter guy.. not a salesman.
