Okay so I have a 05 Canyon 3.5l z71. The only "mod" is I'm running 31x10.5 on the stock wheels. But new wheels and larger tires (33x12.5) are on the way with a 4in suspension lift. Well I'm really wanting to put a little pep in her step before all that though. So should I get a ported TB or a Volant CAI with the ram intake? Or dual mbrp exaust with gutted manifold cat. Which one of these should come first and in what order should I add the others? And when down the line should I get a tune?
