wow congratulations my dream is your reality.:)

^ LOL. Congrats on the new car bro. but i dunno how to adjust the boost or anything like that.

i know on a turbo car you have a boost controler, but as the dealer on that one.

On a blown engine, like the one in the Cobalt SS 2.0L, boost is controlled by speed of the blower. The faster you spin the blower the more boost you will produce. A way you will increase the boost is by shrinking the blowers pulley diameter. Or you can get a bigger blower, I dont think you want to do that though. You will need the stage 2 kit first though cause the injectors you have will not keep up with the new fuel demands of your engine with the increased airflow. The stage 2 kit already comes with a smaller pulley that will increase your boost by 2 psi.
