Way to go RamSmoker!
The dealer has NO right to void warranty. They only have a right to not do repair work IF they can prove that the mod caused the failure in question. If my windshield wiper motor went out, they couldn't not fix it because I run the Predator. The mod has to cause the failure and even then it doesn't void the entire warranty of the truck. Somewhere in here a couple months ago I actually posted the law and it's pretty cut and dry on that.
Glad to hear it's working out for ya!
