So I had a bully dog tuner for my truck and haven't had it plugged in since I got a new engine installed a few years back. Found it today and found someone who would buy it. Contacted bully dog and found out that I would have to change my tuning to "stock" to be able to unlock the device so the guy could buy it from me. I told them that my truck was already stock and they said that I just needed to run the stock tune to be able to unlock it. So I did that and it cut my engine power and turned off ABS and Stabilitrak. Cant go over 25mph, truck shakes, sounds weird. I have no idea what to do and their customer service is closed for the night. I have work in the morning, any suggestions?
