i put a cinder block in my car and let it rest on the gas pedal so it would be wot, and i go under the hood to lookit the throttle valve, but its not open all the way. it seems the cord can be pulled even farther than the limits of my gas pedal (the floor stops the pedal from going any farther). should i try to adjust it so that the throttle actually is open all the way when im flooring it? or is there a purpose to why its set up like this
