Hello all, I have recently purchased a 2013 3.7 with auto trans. So far I have just done a 4.10 gear swap and loaded in the 87 octane tune that comes with the SCT X4 tuner, but that alone has lowered me ET from 15.03 to 14.06, raised my 1/4 mile MPH from 95.3 to 99.08, dropped my 60 foot time from 2.35 to 2.15 and that's on 28 inch street tires. Still getting an average of 21 MPG city and highway combined and loving the 4.10 gear grunt. Looking forward to doing a proper tune and adding a long tube header exhaust this winter and being ready for next spring.
I have enjoyed reading some of the posts here so far and there is a lot of info.
