I just installed the Superchips programmer on my H2 over the week end. Programming was very easy and there are noticeable changes to the performance of the H2. The biggest gains are at higher speeds and rpms, passing, down shifting and the biggest is that the torque management is gone! We all must remember that programmers on the market today can not change any of the factory parameters more than 15% up or down, which is the safe margin of change. BIG-C
