I think our cars do relearn after a while. When I spoke with a tuner he mentioned that they give the ecu parameters, and put in a target a/f but the car does adjust timing and other factors accordingly. Chances are your car just isnt giving the same timing or a/f all of the time depending on weather conditions and your previous commutes. Unfortunately I cant think of a real way of testing this unless you were data logging constantly. Now that I think about it.. I would just have your tuner log your car for the next week and see if he finds anything.
