Honestly, I used Superchips with my Mustang...and the results weren't good at all...especially since I had a blower on top a cast 4.6L bottomend. Thanks to their brilliance in setting my shiftpoints (swapped gears and tq convertor same time) I not only lost one trans, but also a motor when my car spun up too high on numerous occassions. Perhaps, partly my fault for driving it with an incorrect tune, but they had more than three attempts (none of which had good shiftpoints). First was too rich (bottoming dyno a/f meter rich), second was too lean (not going there), and the third was just getting right...but with their bureaucracy they've got running over there, it was nearly 8 months later before I got the third chip, and the shiftpoints were still incorrect (which were supposed to be addressed in the very first, and in at least the second).
Good luck, but I wouldn't put much faith into them. I guess it's pretty hard to "guess" a tune across country anyways, but to the degree they conservatively tuned my car, and with all the :BS: they put me through trying to get the right tune (saying there's was perfect, and there was something wrong with FLP's dyno)....I'm just not going to say anymore.
Hope your luck is better than mine, and just keep that 30-day return policy in mind when it's nearing 30-days and you have yet to see your second chip.
