I know the light comes on when you hit 25lbs, but mine stays on! even after you turn off the truck? also When i first start her up after i shut her off and i step on it she roll some serious coal, but the second coal run she is defueling, IE not as much un-burnt fuel. Like the first heavy throttle in that particular driving session. is this because of the 25lb over boost code?? any ideas?
you might want to check fuel pressure. at WOT your fuel pressure might drop too much thats why you are getting a fuel pressure code.
they make upgraded fuel pressure housings with stiffer springs that raise fuel pressure so you wont go below the desired fuel pressure at WOT.
