Best aftermarket throttle bodies for adding a little HP

I'm new to my 03 Cobra and it has the following engine/exhaust mods:

• Stiegemeier Stage V Ported Eaton with 2.76 Upper Only
• JLT Ram Air Intake
• Kenne Bell Boost A Pump
• Diablosport MAFia Mass Air Flow tuner
• Positive Pressure Relief Valve delete kit
• Metco 90mm pulley set
• Gen 3 Killer Chiller with Drag Pack
• Bassani S.S. Catted X - Borla Cat-Back w/ Stingers - SLP exhaust tips
• 170 Degree T-stat

The car was tuned 3 years ago by C&M Performance (Marv is the man). The car produced 486 rwhp and 465 rwtq. Those numbers seem a little low to me for a ported blower car. I'm thinking about getting it retuned.

My question is regarding aftermarket throttle bodies for the Cobra. Are there any TBs that are considered 'go to' TBs for the Cobra that improve performance and add a bit of HP?

I'd like to get this car to the 500 rwhp mark or better. I'm open to other suggestions for worthwhile HP mods in the $300-$500 price range.

Thanks,
Pete
