you mean a fastman tb or a tb spacer?

 

i would assume tb spacer, as there are plenty of people on here that have done the fastman already... maybe not with the 4.7 but you could probably assume it being a comparable increase in power/feel that you see in a 3.9/5.2/5.9

 

srry to say but i have a TB spacer....adn IM TOO LAZY RTO TAKE IT OFF

take a look...its installed right after the intake

the PO said he didnt notice anythign.......so there USELESS

 

does it work/ is it worth it? is the question...

 

thats what i thought just wasn't sure

 

i got one for free so i put it on and have not taken it off.

I put it on the same time i put on my intake, so i did notice a diffrence, but i think it was because of the intake and not the tb spacer.

 

I was actually talking about the tb.

 

the throttle bodies are good for some, not sure how much,


but like i said before


"throttle body spacers make expensive paper weights"
