seat-or-the-pants is the only A/F needed. Tune it and drive it hard. Keep tweaking until it falls off and then go back. It's not rocket science. A basic 440 should blow the tires up w/ about 10 minutes of tuning and nothing else but a 1/2" wrench, flat head screwdriver and timing light. If you want all out performance, take it to the track with a box of jets and have fun. Don't over think it.
