    Adjusting shift firmness without messing up custom

    I have a power programmer 3 I had on the car a long time ago before I changed the motor to a 383. I had a custom tune done on a mustang Dyno and I am happy with it. I was wondering if I could use my old tuner to adjust my wot shift points without messing up my custom tune?

    Do you know if your tuner "locked" your tune? Some tuners will code/password it so it can't be accessed. If its locked, I don't think any handheld will be able to access it.

    Just plug it in and try it. It will / or will not work...
    I'd guess so, & remember to put it back to stock before your tuner makes any other mods... Or it will be locked...
