Warm up the engine and trans to operating temp. In a safe area, hold the brakes really hard, and slowly Rev up the engine. See what rpm you get when the brakes finally can't hold it and the tires start turning. That is the static stall speed. Lousy brakes, having rear disc's, or hard street tires will give you a low reading. Next take it away from folks, hold the brakes, then stomp the gas while watching the tach. Get someone to help and do both tests a few times. During the "stomp it" test, the tach will climb fast, then hesitate a bit before climbing again just as the car starts to move. That hesitation point is the flash stall. This assumes that you can't blow away the tires doing the test. Give that info to Eric and let him do his thing. P.S. Borrow slicks or stickier street tires if you need to. The better info you can provide, the better results you will get from your chip!
