when you buy a tune from differant tuners i understand it can only be changed by the original tuner.now say i have a tune i like but like the shifting setup in another tune,can the dealers look at the tune of another tuner and add those changes to his?i have two tunes,one has a better shifting setup than the tune im using so i thought maybe the dealer whos tune i like could modify his by looking at the setup on the other tune.
