Looking for something that will work on my fathers 454tbi dually. Its auto and 1995. Anybody used anything that would increase towing and/or milage?
I have seen some guys talking about tuner chips for the 6.0's. I would assume They would make them for the 454's as well. Here is the link for the 6.0 thread. https://towrig.com/forums/showthread.php?t=1946 Good luck some of the site in that thread may be able to help you out though
