Pros and cons of the stage2 performance kit for the 06 SS/SC ? And how much is the kit?
I myself dont care much for this kit & it is not worth what it cost plus the cost of installation,your car is supercharged,go with a 5% undersized pully on it,you will get more boost out of it.
I on the other hand think it is by far one of the most reliable kits you can install. It will cost you about $1,000 for the kit with installation if you want to have a warranty on it. About $800 if you install it yourself. Not to bash anyone, a smaller pulley will not help you. If anything might even cause damage to your car. Anytime you run more boost, you have to supply more fuel. Your factory 38lb injectors are just enough to handle what you have now. That is why with stage 2 you get 42lb injectors. Also on another note, your boost controller will not let you boost past 14PSI, so no matter what size pulley you use, 14lbs is all you are going to get. My car with GM stage 2, one step colder plugs, injen intake, 2.5" exhaust, and wrapped fuel lines is putting out 250HP with 235ft/lbs of torque.
