I was having to get around someone today at about a 30mph roll. I mated it and the truck fell on its face and bogged. it didn't down shift and the turbo slowly spooled. This is the 3 or 4th time this has happened to me. Does this sound like a fuel issue, a tranny issue or a chip issue. I have a 99.5 250 with a 4r100 and Swamps Tunes.
