Meth
I have a z51 with a stage E force, x pipe, katech PTB, GM cold air intake and a tune from Vette Doctors. The car makes 550whp on 93, i was wondering what adding meth would give me?? What Hp increase, and would i have to have the tune adjusted or could i leave it? Also Edelbrock said they would void the blower warranty if i used because the meth would remove the coating from the rotors

However, meth is usually added together with other changes to increase "boost" (technically it's airflow). So a pulley change, or pulley and long tubes. Or in ECS kits, removing the restrictor usually would be done with the meth kit.

You’ll def need a retune. If I was you I’d pulley down and up the boost 1-2 psi at the same time you add meth, between doing both with a retune you’ll jump about 70-80 whp. Otherwise with just meth and retune I’d say you’ll gain 30-40 ish. It would run to rich if you didn’t retune it, I was in a similar situation and it caused me to lose 15 hp with the meth in vs off because the car was too rich. Retune is a must! Still waiting on your new tire review

I have the A&A Si blower and they said it would be around 570 without meth. I added meth for some safety and additional hp and ended up making 610 to the wheels.

Adding meth without adding boost is kind of a waste of money and time. You'll just be able to add a few more degrees of timing and that'll add a little bit of power.
Now...adding boost and using meth to supplement as a fuel is where you'll see 50-75 hp gain. Get to 10-11 psi and add meth and you should see ~650-700 rwhp depending on transmission.
