Ok, so I have stayed away from throttle bodies/spacers/plenums because everything I read said wait til tier 3 or 4, but now I am starting to get mixed reviews about where I am at. Some people say to do it because I have duals/L.T.s/CAI, others are saying it won't make a difference without boost, and others are saying I will need a tune afterwards to feel the difference. Some people say get a plenum, others say spacer, others tell me just get a bigger t.b.
I am wondering if anyone can tell me from real world experience, what they did here and how it worked out. I am not planning on using a S.C. anytime in the near future, so I am not sure which or what sizes to get, if I were to look at doing the upgrade. What I have read so far points to my best possible option being this: http://www.accufabracing.com/accufab...-throttle-body
Thank you in advance for your advice on the topic.
