I had a bully dog on my dads 02 for a little while.. Not very long.. It was the one that fit the 7.3, 6.0, and one more.. After i uninstalled it (did everything the programmer told me to do), the truck ran fine.. Then it started acting up.. It would crank and lope bad until i gave it some juice, then it would idle fine.. Then you could give it gas and it would barely go like it was getting no fuel almost.. Had the fuel filters replaced.. Still done it.. Took it to get the recalls done monday.. They said that it was due to the programmer and that even one time the exhaust temps were over 600 degrees.. Thats what the computer told them anyways.. Anyone else experience this?
