I found my notes from when I did mine. I picked up an '05 computer and confirmed it had NO anti-theft system w/ Joe @ 918/456-2541, I have NO recollection of who Joe was/is or who he worked for. The computer I picked up had "in system vehicle locate tracking", again, I've forgotten what significance that was or even was significant.

The computer had to be flashed for my truck, axle ratio, tire size, etc.

Street and Performance deleted the downstream O2 sensors when they did mine, that caused me some grief later on.
