Re: 29 Mpg???
I've kept exact mileage since I bought the car and with mostly highway driving rarely get less the 26-27 mpg, even with bursts of highly illegal speed. The best I got was just under 31 on a 150 mile trip where I had to stay at 55-60 because of the two lane roads.
I just installed the K&N and have a 1800 mile round trip planned from MI to CT. I'm curious to see if the extra air flow helps the mileage and if I can keep my foot out of it and the car at 70-75 most of the way.
By comparison, my SRT6 peaks around 23-24. Of course I have the tendency to WOT at least twice each tank of gas. This last one saw a little sprint to 150 which does not help the mpg.
