Just wanted to find out from experienced H2 owners if any there is anythign that will help with performance, and increase fuel economy?

I have been told to get a Bully Dog chip (performance computer), and that the Cold Air intake would also help. I was also wondering if putting a more direct exhaust would help?

Looking for any advice on the subject!

Thanks a bunch!

Barry

Didn't do any mods to my H2. Know a lot of guys that did the things you are talking about and got some performance pop. Mileage went from 11 to about 12.5 as I am told.
