Got to pay to play.

First things first. If you "chip" a car and then remove the "chip" after it breaks and tell the dealership that it was not "chipped". Pretty sure that is fraud. I am not a lawyer and do not play one on TV but sure seems like it to me. If nothing else it is just wrong.
Modifications and warranty are complicated. It is not as easy as saying "your car is modified and your mirror fell off, we will not pay." They own the responsibility of proving that they modification caused the failure. In the example above. BMW would have to prove that the exhaust caused such a horsepower increase that it cause a halfshaft to fail.
So with the case of the ESS tune. If for some reason the tune caused a rod to blow out the side of the motor. Then BMW could and would have just about every right to tell me to pay for the new engine myself. That is one of the nice things about Dinan. While BMW warranty now longer honors Dinan mods. Dinan does provide their own warranty.
Pay to play. If you don't like the risk, then don't fiddle with the engine.
