Well, I got the new software on my H2
and it seems to work great, I have seen an improvement of 2.7 MPG on the interstate at 70 MPH for a total of 15.8 avg/MPG and on the city it gain 2.1 MPG to a 12.2 avg/MPG
I'm happy with this improvement and now I'm adding an AIRAID intake system which they claim will improve performance
I will post the results after I have installed it.
