Remember to drive your H2 exactly the same as you drove it without the mods. My customers tell me that they like the sound it makes or they like the boost of power the mod gave to them so they drive there H2 harder than before the mods were installed.
I am told that the use of a programer on a H2 will decrease the mpg and most of the time require a beter grade of gas to make it perform better. Hope this helps. BIG-C
