when I had my AFC I did this 'test' thing where I would floor it at a certain speed in a certain gear. Then I would put the throttle 'gauge' on the afc on and see how much throttle I would need to equal a floored pull. ok, following? example: in second gear at about 3500 rpms, the throttle at I think 50 something % was equal to 100% throttle, however as the rpms climbed you would need more throttle to equal the 100%. I was really bored and wrote down the results somewhere, as my afc has long since been taken out of the sube. But that was when my car was stock and since the addition of high-flow cats, bigger exhaust, headers and an intake, the bogged flooring of the car no longer exists.
