Re: NA Supercharger
They used to sell the same snake oil back in the 70s. Add a $9.95 gizmo to your carburetor and get 70 mpg. I never figured out why Detroit did not buy them up, add it to every vehicle, and eat the Jap competition alive.
Other than a CAI and maybe a ECU reflash, there's not much you can do for reasonable money to boost performance. Just enjoy the ride.
PS - Buy an SRT6. They're getting cheaper and cheaper.
