I have been reading up on a ton that has been said about the trifecta tune and I have decided I want to get one in the near future. Upon looking at their website, I am confused as to what I am getting in some of their packages.. For someone who has desires of putting a K&N intake on their bone stock cruze along with the tune, should I get the trifecta advantage? Also, what is the difference between the trifecta advantage "Stage 0" and "Stage 1" packages? Does the Stage 1 just make the tune work with a K&N intake? Does it include the intake so i don't have to purchase it separately? Or does the cheaper "Stage 0" option work with a k&n intake. There is about a $200 price increase between the two options, so there must be a valid reason for that. Help is appreciated!
