Not necessary. There might be a few HP to be had upgrading to a 52mm TB, but in terms of $$/hp it's not a great investment.

Couldn't hurt to get 24pph injectors either if you are planning on using the stock TPI setup on a 350. Not sure if computer reprogramming is needed for that or not... actually doing this myself now with a stealth ram!
