Tunes can be switched back to stock for warranty work either with a flash or having an extra ECM! No real way for the dealer to tell that you take it in and out.Can you tune without voiding the warrenty? Id hate to be SOL should something happens.
Besides, nothing seems to happen with a tune but without? the odds do seem to increase.
I also change oil at 7500 and fuel filters at 15000
