NEED HELP! could a tune burn up a piston? I need to know from any of you guys that are professionals at tuning whether or not the tune on a car could lean one cylinder out enough to burn a piston up? Also if i took the car to someone or the computer could they look at the tune and tell me if this one cylinder that burnt up was way too lean. I need help on this bad so any feedback is greatly appreciated!!!!!

If the tune is set lean OVERALL (say 13.5 NA or 12+ FI) the issue you might see is the rear (5 or 7) cylinders going lean and burning something. the distribution is not perfect in any engine, and the rear ones have some minor issues in the LSx engines, especially in FI and N2O applications
If not, you need to look at the particular injector where the problem is. You don't tune by cylinder.
