in order to void the warranty because of the cam, they have to prove that the cam caused the failure. for example they cant say the installation of a cam voids the warranty on replacing a power window motor

Just ******* 6.0 it and get done with it. It's cheap as **** if you install it yourself. I get better gas mileage with the 6.0 too; it doesn't downshift
