Harley,
If you’re able to tune the truck now, there’s no advantage to installing an updated CROM. It’s not like your going to gain additional horsepower from a new CROM. If you want a new tune other then what comes preloaded, talk to a CMR Tuner like Keith, and he’ll get you set up.
Diablosport is a great product as long it’s working, and you’re not considered a one-off. If others are experiencing similar issues, or there’s past knowledge of this problem on others vehicles, they’ll work with you to resolve the problem. But, that’s where it stops.
I get it... it doesn’t make since for Diablo to pull the programming/software engineer off cracking the latest Dodge PCM and or correcting the 2017 and 2018 issues, just to work on your 3rd gen. They’re in the business of selling products, and helping the masses.
I’m not going to rehash my grievance with Diablo, but at least Mike@Diablosport is offering to help. I wish Mike hadn’t gave up on me. Nonetheless as stated before, if everything is working now, leave it alone. There’s huge risk, and no reward.
