i bought a superchip for $190 off a company i found on the net, 190 was the cheapist i could find it, everyone else wanted 200+. You have to make sure to tell them that you want the speed/rev limiter removed on your chip or they wont do it. I really like my superchip(ATX) no complaints here
ive taken it up to 127 so far havent got a chance to go higher. You can take it up to redline in your last gear which should be at least 140+
