   this stuff is like anything if you can measure what you are doing you can sort it out."

Don't count on it! For example, no one but your exhaust valves and piston crowns can tell you what running stoich at WOT feels like. Without certain feedback from the track timer, O2 sensor or even exhaust temps, you are only likely to feel stoich to lean mixtures when you burn your pistons. THEN the car slows down. Even the track timer can be dangerous, so it more than helps if you know what you are doing.
