highlights:
The Stage 1 kit includes higher flow injectors and a new PCM calibration. The injectors give the engine enough fuel to rev higher, and the new engine calibration allows it all to happen by raising the rev limiter to 6700rpm. The new calibration also allows full boost instead of limiting it to a 205hp maximum with the stock PCM.


Stage 2 adds the same injectors and calibration as Stage 1, but also includes a smaller 79mm supercharger pulley which increases boost by 2psi. According to Jim Minneker, Engineering Group Manager at GM HPVO, the Stage 1 calibration is configured to account for the smaller pulley if it is added, so there’s no need for different calibrations for each stage.


We’ve been preaching that peak horsepower numbers don’t mean a thing for years, and while the Stage 2 package doesn’t deliver much additional peak horsepower over Stage 1, it provides what matters most – torque. We found the torque to be a vast increase over Stage 1, resulting in 10mph more straightaway speed and monster acceleration off corners.

Thats cool at least I can just get stage 1 then buy a pretty billet flow blue pulley to slap ontop of it

I wonder if that means that they'll have a belt for the smaller pulley. I really hope they don't leave the Red Line out of it and just give the upgrades to the GM vehicles.

Hey this just popped into my mind: It says that the new calibration allowd full boost? Would this mean that you could snap a 3.0" pulley on there and the supercharger would give you the full 18psi??? Someone enlighten me please

I know this is asking alot but is anyone that is familar with GM's pricing structure be able to meander a guess at what said kits would cost?

You mean chevy right? Saturn is GM. And the upgrades will be for the cobalt and the redline.

i wonder if we could get stage 1 then throw the PSI kit with piggy back and see even more gains!

A Psi-Fi retune of thier powerpaq might be in order but hey, what do I know I'm an idiot

So, for those of us with the smaller pullies... we just need the stage one setup, and we have both stages huh? Interesting... and a 6700 rpm redline...

I think it means no more boost bypass mods are gonna be needed
