I've been looking everywhere and I cannot find a stock BIN file for my 03 Regal GS...

The OS is 12583378

I am a serious newb when it comes to tuning. I downloaded TunerPro the other day and have been playing around a little, but I'm interested in seeing what exactly is inside the the box, so to speak.

What do I need to pull the data off of my PCM myself?

Laptop - check
Tuner Pro RT - check
Cable - don't have one yet....
Other software - ?
EPROM programmer - ? I'm not opposed to buying one to play with.

I'm actually an IT guy, but some of the stuff I'm reading is way outside my normal day's work....

Any help would be great.
