boost, compression....etc

I have a 99 firebird formula, and recently bought a d-1sc serpentine kit, 42 lb fuel injectors, and a holley fuel pump. Everything is stock on my car, just wondering how much boost i could run on it, what compression ratio is best and how to go about getting it there

When you go into boost, 11.5 to 12.0 is a good place to be.

These are basic guidelines and should not be used as an exact science. I am not nor do I claim to be an expert on the LS1. I did design my engine, and feel that I can make the above statements based on experience my own experience with my own car.
