The only way a TB spacer or intake works good is with a custom tune.
I was cleaning my TB and intake this past weekend and I thought I would just leave the TB spacer out b/c of the negative feedback they get. Well after I took it out and drove it for the day, I put it right back in as soon as I got home. My truck ran like s**t.
So if you don't plan on getting some customs tunes from an Xcal 3, then yes don't bother paying for an intake and TB spacer like C.B. said.
