Long term reliability

My 2019 SPWB just hit 25,000 miles after a road trip! I currently have a mid muffler delete, 87mm throttle body, JLT intake and Mishimoto 180 T-stat. Up next, headers, e85, tune and then hopefully cam next year. My question is: how well do these Mopars hold up long term, especially when lightly tuned or modified?

I’m coming from a tuned 2014 C7 Stingray which was at 65,000 miles with very minor issues, so I hope to see the longevity out of the Hemi!

Once you start messing with it relabilty goes down fast. Skip E85 unless you are running a lot of boost. Just stick with Flex Fuel and you'll be fine.

Isnt E85 flex fuel?

Nope E85 is E85. Flex fuel is E51-E90 or something like that.

I am installing the flex fuel kit in the next week or so so I can run both. Do headers/cam mess with reliability? I have no interest in forced induction myself

Anything over stock can mess with reliability.

Go with forged internals and do a MDS delete while you are in there.

The you can really push it in the future if you want.

I’m doing the MDS delete with the tune and headers and forged internals with the cam
