2013 duramax error code

[denverdale]

While returning from Kansas yesterday, I noticed a check engine light was on. Today I read the code and it is P2599. I have not been able to find a list of codes so far. Does anyone have a list they can share or know what that particular code indicates.

Boost Control Performance, circuit high.

Unless you have a Tech II handy, it's an issue for the dealer or a competent shop. Certainly warranty, if that's an option.
