now i havent seen an LS1 thottle body, but the thottle body on the trucks have a little half moon thing when the valve is at 100% that restricts the flow quite a bit.
I drilled the rivets out and removed this piece and then filled in the holes where the rivets would be.
and i can feel a decent power increase at 100% throttle,
i dunno if the ls1 has this little piece but i bet if you remove it you can get a good increase in power
just a thought
