Performance tuning revolves about matching the sensor
calibrations and the commanded fuel/spark (and shiftpoints,
and whatever) to the car's mechanical realities. "Canned"
tunes only fit as well, as the vehicle matches the recipe.
Not to say that GM couldn't, or shouldn't produce some
performance tunes for dealerships to apply, but my money
is on "won't".
Fortunately there's the aftermarket.

that would be a slick trick. But, as stated before, the biggest gains from tuning are because the tune is matched to the car. Similar philosophy to picking a cam shaft. Off the shelf might work, but having a cam matched to the machine works better.
