Since the AEM was pretty much done anyways, I guess I could have the AEM completed, get it tuned, and hold off on the agreement/refund for a year or so to see what happens. I can't imagine the 2018's drive like these now do. It's scary until it warms up (even in TX summer) and just bad after that. Makes you wonder, as speculation at first was to just replace it with the 2018's software. . . and they obviously went way overboard instead. . .so are their 2017-2018's toeing the emissions line so close that they were afraid to draw attention to the 2018 ECM?If I were you I would complete the emission update, collect the refund and go get it tuned. But it would leave you out of any further actions taken against FCA in this matter after signing the release from. I think there's more to come, these are just my though's.
