looks like I am getting about 12 mpg.. not quite what I wanted, but the C6 is killing me.
I also am turning 3K at 70ish..
I am seriously considering dropping to 3.70 gears from the 4.11's. The dual tcases will give me plenty of crawl off road with the auto, and dropping the R's will be good too..
I also installed a tach int he stock hole, a radio (HD) and a CB.
