Is there any tuning to be done on a stock motor?? Most of what I read is that GM's tunes are rich so I am wondering if something should be done on a stock flash???

the tunes for year/model are identical. The different hp levels you see on stock cars are simply small mechanical variations and/or atmospheric variations.

Any experienced engine builder will tell you you can build two identical engines down to the nitty gritty and they will NOT dyno the same.

This. I swear my 10-second Z28 was built on a Wednesday, while Scott Settlemeier and Bob Lutz were visiting the plant. That car was a factory freak.

My Redline... not so much. It may have been built on a Friday before a holiday weekend. :D
