This was designed on a stock motor with perfectly healthy injectors and fuel pump, so by the time you hit fuel pump you may have already hurt your engine from running lean.
I have personally hit fuel cut several times when I was on 360s without any noticeable damage, but you are at your own risk to depend on it to save you.
That is why you absolutely must have a logger. Even if your damn car is stock spend the money on a logger and see how your engine is doing.
