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???
Stock flashes had variance depending on the car. I've heard some with the stock 205 and I've heard others up to 230. It all seemed to depend on the flash. There is always room for tweaking but the stock flash was more or less maxed.
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.
