I had a Diablo on my Charger SRT8. It made a huge difference in power with some mileage gains. I bought one for the H2 last week. Installed in yesterday. Seems to have made a power difference. We will have to see about mileage as I drive more. I've been pretty consistent around 12.6 so we will see if that goes up.

ok i have went with a superchips. i run a trip home stock ( 670 miles ) and averaged 11.9. then another trip home with te tunner and i averaged 12.7 not much but better than nothing. my next mod will be an exhaust.

Didn't make much difference power wise, but some. I installed the 91oct tune. The mileage stayed about the same as stock, but did have some performance difference.

I installed the 87oct tune yesterday. Performance dropped some, still better then stock. So far the mileage seems up about 1.5 in the city. Haven't been on the highway yet.
