Sounds like you could have a bad map sensor..

 

Its normal to get such a code with a high HP tune (chip, tuner, etc). Its indicating overboost over stock and the code indicates the truck is switching tables to defuel. You can eliminate it with a overboost kit (basically, a by-pass) if the code bothers you.

 

Where do we get such over boost kits?
