How does it work? What does it do? How does it work in conjuction with a HEI system? I have a box, just the box, can I run it with the stock HEI on my car? Why would I? What would it gain me? The car is an 87 Corvette with long tube headers and 3" exhaust. A supercharger L98 TPI engine with 8 pounds of boost. Thoughts?
