There really hasn't been to much engine failures with these tunes. You start getting into trouble if you really start pushing the envelope by increasing boost over 20+ psi. As for warranties and detection issues, it all depends on your relationship with dealer. If you have on of these tunes installed, remove it before going into a dealership if you're going to do major work to your car, no matter how much you know them(turbo replacement, wastegates, fuel-pump,plugs&coils, etc). If its light work like(oil change, brakes, air filter, software updates, etc) in the most part you'll be fine leaving it in.
