Let's see.
The good:
1. You get to talk about it.
2. Perhaps a cool sticker or T-shirt.
3. That's all there is.
The bad:
1. It costs money.
2. It defeats any tuning, resonance, harmonic etc. benefit from your intake manifold and air box.
3. It may (not sure) cause problems (reduced vacuum at certain throttle openings etc.) that the ECM will not recognize.
4. You're telling the next dealer/shop "anything wrong is my fault since I installed X", which they are happy to hear. It means they still make money, but are not responsible for a failure.
5. HP added: none.
Summary: don't. TB size is a legacy from the V8 days: "take off that 2 bbl. and put on a Holley 750". It already has a 750.
