My truck is an early 99 f350 with the 7.3 diesel, I orginally had a bullydog 4position chip which really messed my truck all up(when cruise was on the truck surged really bad, trans shifted early then late, sometims not at all) so i tore it out and the trucks runs like it did when it was new but now i just want to do it right so i will be satified when it comes to towing my many trailers. I haul stuff all the time. so please let me know what i can do to get my ford towing strong.
