I bought a SCT GTX and it fried both of my batteries. I called SCT and sent my GTX back. I then bought two brand new batteries and waited for them to return my tuner or a brand new one. Mind you I’ve had the truck for a year and never had a single problem with it. I got the tuner yesterday and called SCT before I even plugged it in. My volts were too low to program it but the tech support employee told me it would be fine to run gauges with the voltage that I had. I drove to work no problem, but on my way home the truck was shorting out and finally died on me in the middle of the interstate. My truck is currently parked on the side of the road and I need help knowing what happened and whether or not SCT will help me with my obviously fried PCM. Once again I never had any problems with the truck until I plugged up their tuner.
