I've been staying out of this
... etc ...
but now I want to TRY to clarify a couple points.
If you have canned tunes, and have set your truck back to stock before the reflash, the programmer should work fine when you get the truck back.
... etc ...
If you have custom tunes, they are written to modify the individual stock calibration YOU have in your truck only.
... etc ...
So finally, before taking your truck to a dealership, ALWAYS set the tune back to stock, regardless of what programmer you use.
... etc ...
If you are taking the truck for an emissions test, DO NOT change the tune back to stock. Emissions testing does not test the "tune",
... etc ...
I know, it was a long read, but hopefully it clears up a few points.

Well, I have learned more about programming/programers since I started this post. To actually end this story (kindof), was the cams...compression on each cylinder sucked. Of the 8 cylinders, 3 were between the 150-170 psi (good compression), 4 were between 90-130 psi, and cylinder 7 had no compression. Explains why half of the motor was not working (barely working). I am removing the Vortech Supercharger and probably selling it. Also, I'm replacing the Comp cams with OEM. In doing so, I bought the Predator PC Interface Kit for future tuning (and experience). I know I'll have to do some tuning with it being a built motor, extra fuel, bigger tires, gear changes, etc. I will update again sometime next week.

I am spending money to get my truck back running. Most of you are just like me and can't afford to not have a running vehicle. So, if removing the procharger to fix and determine the problem is the best option...then i'm going with that. Right now, I have too many variables and need to get back to the basics.
Now, once the truck is finally up and running, I can put the procharger back on with a custom tune and go from there. As noted from before, I am learning more everyday and once the truck is actually running right...I start playing with the mods again.
