Not worthless, just incomplete data incorrectly linked to model-year and configuration. Mostly for pre-gens and some new-gens snuck in there. What wasn't reported was before & after behavior. "Smooth and civilized" tend to be too rich and slow. Max-power tuning creates a raw, temperamental rough beast that's faster, but more difficult to manage. Remember that '60s hot-rod saying... "Lean is mean!"


P.s. altitude requires smaller jets.
