You can purchase the parts of the kit with these part numbers, but the necessary software flash can only be installed through a dealership, so it will not do you any good. The instructions have an authorization code, and this code combined with your VIN is what is needed to install the powertrain software into your car.
There are several software calibration files, depending on whether your car is a Solstice/SKY or HHR, manual or automatic transmission, and whether your car has a brake vaccuum pump or OHB.
The kit is emissions legal in all 50 states.
How is it installed?
The TMAP (Temperature/Pressure) Sensor on the post-charge air cooler/pre-throttle blade tube, and the MAP (Manifold Air Pressure) Sensor on the manifold are replaced by the same Bosch TMAP sensor above. These sensors are an off-the-shelf part, and prior to install require the O-ring to be replaced with a thicker O-ring.
Your old sensors are cut off, and the new sensors are installed using provided adaptor harnesses and shrink wrap.
Then, your car is flashed with the new software through an internet connection and a Tech 2. This calibration is released by the authorization code and your VIN, and can only be installed at a dealership or other authorized service center.
