is there anyway to change the shift points in a 90 f150 with the e4od tranny? i know i need to regear as i only have 3.08 gears now but even heavy on the gas it still only shifts at 2700 or so. its almost a complete dog and not even close to the powerband for the motor.

 

In another thread here a few days ago a guy said he was able to get the shift points reprogrammed by a custom tune.
