So the theory would be that the mass air reads more air coming in and adjusts some global parameter to avoid leaning out?

The 04 also shuts off the fuel when you are coasting and helps slow down, my 01 did not do that. Having a wideband was quite an education.

That's a very interesting observation. Obviously the 04 program has been fine tuned for additional compensation. Obviously, a team of programmers and millions of dollars versus Mickey Mouse Tuner (not all) flying by the seat of his pants will allow you to get very interesting results.
Would an 04 computer fit on previous years?
