AEV procal worth it?

    So I'm thinking about an AEV procal or superchips and was wondering if its worth it. I'm just really looking to move the trans shift points since going with bigger tires but was wondering if it actually makes a difference. Any mileage increase? drivablity? First hand info appreciated. Cheers, GAP

    I used the procal for changing the tire size and the “alignment” feature. I don’t feel it made a difference with shift points...only speed calibration. If you are looking for “performance” gains, you won’t get that with the procal
