I removed the muffler from my truck and the cat fell off and now I am hitting about 25 pounds of boost without much effort . So the questions is, what is a safe amount of boost for the 6.0?

I know there are alot of people who have modded their trucks and are getting some serious boost but what is safe. Is there a maximum setpoint set at the factory?

I have an Edge A2 that I mostly run on stock or 1. I bought it mostly to watch what the motor is doing. Most of the time I don't even look at the dash just at the A2 for EGT and engine stats.
