MTI or TPIS or BBK throttle body
The MTI one is a far better piece than the BBK one. The MTI one is machined out of a block of billet aluminum, and polished to a show-level look. The BBK one is just cast aluminum with machined holes.
Haven't seen a TPIS one yet.

tpis has stock ported throttle body's that are cnc ported and will add a good 10 t0 12 hp or you can go a step further and get their billet oval tb but you will have to send in your intake for modifications to the front of the intake [to fit the bigger oval] i have the oval on my car and it looks and works great,better driveability too especially with bigger cams.
On a LS6 intake, you probably wouldn't benefit with any of them when compared to a good ported stock TB, IMO. (The TB opening is only so big, so the larger TPIS and BBK TBs are wasted on it, and the MTI is nothing more than a "Show quality" ported stocker. Yes, I know its billet, and its not a "stocker", but still. I have yet to see any improvements over a ported stocker at 1/3 of the cost, although it is very "blingalicious" 
) Also, a ported stocker is ~$130, so you can spend the other $250+ on a mod that will actually show a gain, IMO.
