P2263 (turbo boost performance) running 310 tune at idle

[elibenson]

I am getting a P2263 (Turbo charger boost performance) when I leave the truck idling for more than a minute. It doesn't do it every single time, but I have got the code about a half a dozen times now. It only sets the code at idle. I don't know if it is because of the 310 tune or not. I need to re-load the 275 and see if it still does it.

I am wondering if it has to do with the EGR valve cycling at idle. Or maybe I have a faulty MAP sensor that is reading too high at idle. Does any one have any ideas? I don't want to have to take this thing to the dealer to have it looked at.

Mine does this on the 275 tune. I was wondering why it does this too. Any suggestions anyone?
