4.7 magnim 5spd SC 4x4

I am currently running a full exhaust system and a 180 thermo. I want to upgrade my TB so i was wondering what my options are and what is the best route to go how many MM. If i upgrade the TB do i also need to install a CAI. I was on the fastman TB site http://www.thefastman.com/Throttlebodies47.asp and was wondering if this was something worth purchasing.

thanks

 

I would do the CAI first, but if you want to do them both, they are both great upgrades themselves, and will work even better with more aggressive upgrades in the future.

 

all depends on how much you are going to build it up to what size tb you want. Call up dan "the fastman" or email him, tell him what your plans are and he can point you in the right direction. He'sa very cool guy to deal with. BTW i have one of his tb's on my RT and am happy with it right now, that is until I upgrade to my 408 or supercharge it, then I'll have to shell out the $$$$ for a good one. But for the price, you can't really beat it.
