Hi everyone, I just installed some 22's w bfgoodrich 325/50/22 AT's on my 03 H2 i found a great deal on a Hypertech Power Programmer $125, can anyone help me with the settings i am very new to this and dont have any idea how to do this. Is it something that is good since i have the new wheels? I put a magnaflow exhaust tuned down whatever that means?


Thanks
