Please give me your opinion of the following timing tables. Do you think they are wrong for a turbo ls1 running 5psi - 9psi boost?

The High Octane looks a little high, but it really depends on what type of gas you are using, compression, and what altitude you are at.

Some of the high altitude New Mexico and Colorado folks can run N/A timing at 8 lbs of boost with little to no problem.

For a sea level, pump gas car, I would think 25 may be a few degrees to high, but it depends on several other factors.

Good Luck

I live in Las Vegas I am a stock motor 10:5 1 and using 91 octane on 5psi and 50/50 water methanol to help cool at 9psi.

That is probably a little high for 91 octane gas. Personally, I wouldn't run it any higher than 19 degrees, considering your ambient temps and the fact that you occasionally boost to 9 psi.
