Get rid of the Banks...j/k. No, some programmers will throw the code no matter what. I am assuming that your dad's truck throws the code after a long hill that he is pushing that boost. If he doesn't lose power, it is just nothing to worry about. From what I understand on this problem, the computer sees too high a boost for throttle position and then throws the code. My truck does the same things, but it seems to be coupled with cold here in AK. I have only seen it twice. I know there is supposed to be something from PPE that is supposed to eliminate the code, but it is pretty expensive. I will just live with mine since I have a predator to clear the codes.
