I assume you've contacted Titan to see if anyone else has been having this issue? If so, that might give you some leads. Also, are you sure the tech put in 50 gallons when he reprogrammed it? Perhaps the programming didnt save? When the tank is full, what does the DTE tell you?
I'd like to know if you get this resolved because I was seriously contemplating one of these for myself. 26 gallons is just stupidly small for a truck thats meant to tow.
