I have just recently added a K&N FIPK air intake and a Superchips Power Programmer to my 2003 H2. I have had it on for a few weeks now and haven't noticed any increase in my gas mileage, actually it has gone down. I was wondering if anyone knew what the best setting on the programmer was for the H2? Right now it is on the highest setting and I believe that is causing my mileage to be bad.
