bully dog chip, cold air, and exhaust on H2

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!

Exhaust, CAI, Chip and of course Supercharger!!

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.
