From GM there was no stage one or stage two. GMPD only offered the GM Performance Turbo Upgrade. There is and will not be any second GM edition since they stopped building the HHR.
In some GM storied they would use the Stage 1 but it really was never the offical name.
Now many also confuse this with the Cobalt SS Supercharger Stage One and Stage Two. GM did make and advertise this kit as being two stages even in their catalogs. But then note it is the Supercharged engines only.
