What is your part throttle shifting like? Any way to vacuum modulate the shift firmness? I mean at 2500 rpm when you shift is it just as firm as if you were 6500 WOT? Also just your opinions? Its either this or a damn expensive controller for me....
Light throttle shift are firm depending on you converter. A high stall converter will dampen some of the firmness. At higher RPM the pump is putting out it max pressure. What do you consider expensive for controls?
