I'm breaking 100k miles on my 14 Grand Cherokee. What is the life expectancy of the engine? I am fully deleted, so I wont have to worry about buildup from the egr or anything. Has anyone made it 200k and beyond?

I would like to know also. Im looking at a 2014 Jeep GC 3.0 90,000 miles. Went to look at it. Had a recall on it. W41 would npt go out of 3 gear from what I read this is the 3rd update sent out. Screen displayed 100% exhaust and a throttle control. I have been debating on getting it or not I said they're going to take it to the dealership and fix it

2015 GC here: 112k miles now. No AEM, no mods; running Rotella syn 5W40 since 20k miles; running Power Service silver or white depending on season; no short trips.
Not one issue, ever. Must have gotten lucky?
Only had one flash that changed trans shift points so as to not lug, 2016? Not sure what that upgrade was called; it was around the same time they changed the oil specs for the 2016s.
Other than that, I've refused the problematic AEM.
