performance questions

I am going to intstall a trd cai and was thinking about installing a throttle body spacer also. I havent worked on trucks that much but i know how to mechanic a lil bit. I was wondering if anyone has installed a throttle body spacer and if it is worth doing it. What kind of increases does it give and how difficult is the installation

Stock intake plenums utilizes ACIS to control runner length for optimal performance through the full RPM range. A TBS would only produce gains where the longest runner length is needed. In return, when a shorter length is needed you'll be making that longer, and could hinder performance.

My advice, skip it and move on to the next mod.

 

yep waste of money!
