So I gotta 96 f250 powerstroke with a e4od that's gotta billet 5 disc tq converter, shift kit and extra clutches in the OD. And I'm running 35s but have recalibrated my speedo to my tires and my truck always likes to up shift too early when im pulling my horse trailer. My f150 e4od dis the same things. Has any found a solution to this?

 

Push the gas pedal down further or get the truck re-tuned. Those are your only options.

 

Hmm I have a ts 6 position chip. Know of anyone that could burn in a new shifting program?

 

The person you bought your tunes from should be able to change the shift tables.

 

Ok. Buuuut I have no idea who that was it's been a while
