Is the warranty still valid with the Green Diesel tune

I'm not sure. The GDE tune is EPA and CARB compliant but the words in Ram's warranty tell me it voids the warranty. To get an official answer call Mopar Warranty, don't rely on what gets posted here, unless the poster provides confirmation.

Yup

If so, That would be great. Can you provide any proof of what you say?
