Lets clarify. They dont do chit on a fuel injected vehicle that has an injector per cylinder. They do however make a small gain on a TBI vehicle.
its only useful if your throttle cable is a little loose that is the only reason i am getting one only good on cars/trucks that have a carb or a throttle body with the injector on the throttle body
If your throttle cable is a little loose than go under the dash and pull the slack outward then take a wire coupling connector and crimp it on there in a couple spots... no more slack!! I want one just so I have the "poor mans turbo" sound!!!!!
