Hello all, I need some help figuring out what this code is.

A friend of mine got this code that tripped the CEL, and on the code reader, it says:

Cold start
Turbocharger/ supercharger
Boost control 'A' performance

No other symptoms, stock truck.

The only other associations with that code I can find are related to the EGR.

There isn't a dealer or mechanic nearby, so I'm just trying to figure out if this is worth worrying about.

I have a hunch it's not.
