The biggest problem can be from program glitch that stops the engine from running such as returning from program to stock.
If you get into this situation, the only way is to have a dealer reflash the PCM.
Then the question is what's wrong?
The other position is when you program parameters outside of the reccomended settings and get/cause yourself problems you don't understand about.
There are certain elements of risk you have to assume if you want to play.
