I am going to install an airiad cai on my 2012 mustang gt. I am going to use it for a while with the mvt insert so I don't need a tune. I will eventually remove it and get a tune. I found an article on it in 5.0 mustangs magazine, and they stated with the insert it ran a tad lean for their liking. Here are the dyno results. http://www.mustang50magazine.com/techarticles/m5lp_1109_tech_inspection_airaid_5_0_cai/viewall.html Would this be safe to use?
