Technically, Dodge and MOPAR didn't make a Stage 0 either so we shouldn't be calling it Stage 0.
We can call it whatever we want but in the end there really aren't many "stock" stage kitted SRT-4's out there. They are all modified in some way most of the time. Aftermarket wastegate, a mapclamp, larger fuel injectors, fuel computers, etc....
The only thing now-a-days that we know for sure with a car is what PCM it is running when someone says a Stage. Other than that, we always need to ask what other mods are done to the car. Just like I tell the colbalt buys, you can run a S1 stock SRT-4 or you can run a 50 trim S1 SRT-4. Big difference power output.
