The only down side to sct that I'm aware of is the expense of having to pay to have it programed, and pay again when you want to tune a different car/or to have it unlocked from the car you currently have, and after so many unlocks I think its useless after that. (I may be wrong on that last part and its another tuner/software entirely.. so yeah I'm basicly pulling it out of my ass since I don't know for sure)

But the only tuner (guy down in fla) I have experience with ONLY uses SCT to tune.
