Alright, I have been looking into getting a chip and I need help. I was thinking about going with the X-CAL II for my Bullitt, but then I noticed something. They have this thing for the SCT 4-bank chip, which is by the way $100 cheaper than the X-CAL II, where you mount it where your cigarette lighter should be and that is how you change tunes. Has anyone heard good or bad things about the 4bank chip?

 

get an actual tuner.

 

+1 get something you can get reprogrammed if you need to. Haven't heard of what your talking about, but, on my SCT XCAL II I can get it reprogrammed if I add more mods to my car.
