99 F250 7.3 random miss
This weekend I was pulling a gooseneck trailer and had mount tuner on heavy tow mode. I started to pull a pretty good hill and the truck all of a sudden, it was like it died for a split second and of course bucked really hard. It took right back off, but then did it again. I turned the tuner down to stock mode, and it didn't do it the rest of the way home, but I don't know if that was a coincidence or not. Just wondering if anybody has had issues like that? The truck has full force 180/100 injectors, ww2, powerstruck tunes. Has the hutch and harpoon mod done.
