Next week I will be ordering a SCT programmer. What I am wanting to know is what are the adjustments that can be done with it. I have a auto and want it to shift firm. I havent seen what can be adjusted with the programmer for the tranny, All I have seen is shift points. Disabling the traction control with the programmer does that mean that when the car is started the TC is off and can be turned on with the switch? I am going to get the SCT from alternative auto. from what I am understanding they come with 3 tunes. Does that mean if i want to tweak something that I will have to over ride one of the tunes?
