Do you have to do both the stage 1 and 2 kit to get the most power of these cars? What is the approximate cost of this and does it keep your warranty in tact? Im about to buy one of these cars and really want to know what im getting myself into before buying it!

 

 

Unless you are about to buy a 2007 I don't think you have warranty. Just get a stage 2 kit because it has the stage 1 components as well.

 

whats the upgrade from stage 2 to stage 1?

 

Smaller pulley and belt. Injectors stay the same. Tune stays the same. That's it.

 

whats the hp gain?

 

Gm stage 1 is supposed to have 236HP and stage 2 is supposed to have 245HP.

 

i thought it went stage 3, then stage 2, then stage one so i thought stage 1 would be the best
guess not

 

Stage 3 makes the most power.

You are ass backwards man, haha. It's not a car show where #1 is the best

GM Stage 1: 42lb injectors & tune
GM Stage 2: 42lb injectors, tune, 77.9mm pulley, hub, belt
GM Stage 3: 42lb injectors, PCM (adjustable rev limiter, high octane mode, nitrous), 76mm pulley, 2 pass endplate

GM Stage 1 rated power: 236hp 205tq
GM Stage 2 rated power: 241hp 218tq
GM Stage 3 rated power: 248hp (93 octane), 260hp (100 octane), around 300hp (nitrous)

 

ahhhh gotchaaa
i had realized that too after i posted hahah
i have stage 2 where can i get stage 3 at the dealership?

 

You can purchase GM Stage 3, or any Stage kit from Crate Engine Depot. Much cheaper than the dealership.

I've been running the GM Stage 3 PCM & hardware for over 2 years now.
