I know I know I know!!!!!!!!!!!
My truck did the same thing i thought it was the APPS but it was not.....
I had a low boost code, and replaced the MAP sensor (with a used one, lol) and have not had the problem sence, its been like 3 months!!!
There was alot more diag into the MAP that determined it bad, but thats the short version
