are the gm stage 2 and stage 3 refalshes the same or different?

i have 45 ibs injectors and a 77.9 mm pulley, but i think the reflash i have might be for the gm stage 3 package. does his matter?

 

GM Stage 3 adds a little smaller pulley, plus a custom tuned ECM with a nitrous control adder.

basically presetup for a 50shot nitrous shot.

but looses all factory GM warranty.


Stick with the stage 2, drop a pulley and get a better custom tune on top of it...

 

well i just wanna know if running the pulley and injectors off the stage 2 kit with the stage 3 reflash would do any harm because that what i believe has come equipped on the car when i bought it

 

Nah no harm done at all. Stage 3 is a stronger tune than Stage 2 for sure, but it is nothing drastic.
