I need..
 

A little information on computer chips, that add horsepower and torque. I'm interested in what they do, and how it works.

Could I put one into a 1981 Camaro Z28 4 Speed? If so, what website could I look on for some information on a specific chip and how much it cost? Thanks. :) I have seen a Hypertech chip, but I think it was just for a 1981 with automatic transmission..

No one knows anything bout them? :p
