one of the nice things about the superchips is that if you are using an android phone there is supposed to be an app to DL and a BT Dongle(dongle hehe) so you can tune your Ram with your Phone. i think there were working on a Iphone app as well. if you are happy with superchips i would say keep them. they have extensive testing and awesome customer support.
