Bump Stop Mod?
You may well have a bump-stop that allows the blade
to open fully, but a cable with so much slack that you
can't make it. It -all- needs to be snug, and one key
piece from the throttle cable pulley cluster to the pedal
is non-adjustable.
Get the bump-stop to where it will open to dead center
by ruler, then see if your pedal, matted, will get you
there. If not, fabricate a spacer or bend the pedal arm.

...... just make sure you are getting 0% throttle at idle and don't worry about it... jeez; free mods aren't what they are cracked up to be in my opinion. research before doing your mods and think about what can or can't happen after you do them

They probably would have done a heads and cam swap too. I wouldn't bother with those either since GM didn't....

The reason why its like that is the poor quality of cast and molding that they do for the TB's it would cost to much money to get everything right on the car.

Bottom line is, at some point no matter what the car company, they all say "thats enough" eventually, or worse "that's good enough". That second phrase has lead to the demise of many things...
