I'll probably order one of these since $1K isn't a huge cost on top of the price of the 35is anyway.
If your tunes leads to the fault and the dealer can prove that, they can deny your warranty claim. Including Dinan. But, Dinan provides a 2yr warranty (i think) if their stuff breaks your stuff. Most folks return the car to stock tune before taking it to the dealer just to be on the safe side.
