For all who have a 2009 (or '10 I guess) 5.7 Hemi, can you post the MPG shown on your dash right now? Please be honest! I am trying to get a realistic average. Right now, mine is at only 15.6 MPG. It's at about 32k miles, so it's due for new plugs, but I installed the K&N clod-air intake kit about 10k miles ago and hoped that would've helped more. Thanks in advance for your input!
