Jimberg -While your logic is sound, and I read the book that you are referencing, the results seem to be different in real life.
How many people have drove to the strip, ran a few times, and thier e.t.'s improved, without touching the fuel pressure setting? Not many I would guess.
Although the book states the theory, perhaps it just doesnt work as well as it is supossed too in actual conditions?
Why is your computer not adapting? Are u saying your pressure is so high, that it runs good there, because your computer can not open your injectors any slower to compensate, or else it would?
