Detonation is the one I'd be most concerned about. This can be seen as little putting marks on top of the pistons. Not all pistons will have equal detonation as it is a combination of timing, fueling, and cooling. In short, be mindful, and buy modded cars from trusted folks. There's nothing wrong with buying a modded car, and can save you a boatload of money if done well. It can cost you a boatload if done poorly.
When you tune, you're really only changing the target boost though. The DME safety features are still in place which limit boost and timing when it sees values hit a BMW determined safe threshold, like IAT too high etc. These safety features prevent anything like what you're talking about from happening. And this is all before the car goes into limp mode, which is an additional safety feature that protects hardware.
