Before The Tune ??? I did the G5X1 CAM & LS6 P&P Heads and all the other goodies motor wise (no T/C or Rearend yet) but got the car back and it feels actually slower then it was and backfires like crazy. Is this common before the tune. I was expecting it to run bad but not butt slow and sound like a machine gun backfiring so much.

yeah I have decided to do that, I just attempted to drive it once today because I will not be able to get it tuned before I leave for Iraq but I do not want to hurt it and she will just have to sit

i think you shoudl investigate a vaccume leak, coil packs harness on backward or cracked plug... no reason it should backfire that much.( to sould like a machine gun) ...... but each car is different.
