I got 03 standard output 250 horse truck with auto transmission. Pulled over the mountain this weekend and the truck surges on settting one and gets worse from 1 to 3. it surges so bad it slows the truck down so I PUT IT IN STOCK MODE AND FINISHED THE WEEKEND WITH NO SURGE ANY IDEAS? Also when I got home changed fuel filter checked how fast the filter housing filled less than 10 seconds. Air filter is clean.
