Every dealership is different. I got crap from my dealer as a result of my Dinan tune (which is all I had on the car) 4 or so years ago when I had a few things go bad...granted they didn't void my warranty in part because I didn't have any catastrophic failures, but they had on file that I had a tune....so had something happened.....it might have gotten dicey.
