Anyone replace there Throttle bodies

[Cobra1894]

Is there really a 10+ HP improvement with these throttle bodies? What is the best brand to go with? What size?

I went with Granatelli's Piece and the workmanship is awesome. be aware there is some adjustablilty with their Throttle Body. and definately a 10+ RWHP gain with it.
It costs 350 bucks which is not as expensive as BBK's part and definately as Good

My Throttle Body is twin 62mm

will this require a retune?

i change mine,, but thats because there was a problem with mine so the dealership changed it under warrenty, stock throttle body

I put in the central coast mustang one and did a test before the blower dyno and after with the TB installed..11.2hp increase..this is on a blown application though but there was a nice gain

Definately will require a retune due to increased air flow. and Granatelli states he is getting 22 hp and 11 ftlbs increase with his part
