Having always been a Chevy guy, Chrysler vehicles have never been my go to. That changed this year when my son bought a 2014 ram Hemi, he also was Chevy prone. Then I found the 2014 eco diesel in the Laramie longhorn. Love the truck but was made aware of the needed AEM... I have read posts of numerous ones that had less than desirable results. Has anyone had this done to their truck. And I too have had the dreaded radio lockup when the dealer was attempting to do the update. Waiting for the fix...
