I've posted a couple different places, but here ya go, the xcal3 cost about 300 to 400, a custom tune by a live person in your area about 150 and a new cold air system about 199 to 500 depends on what you want, like mine JLT carbon fiber. but my tune guy has done so many tunes he can't count and did my 2010 and another the other day, with exception to looks the new CAI in these new ones are just as good as a aftermarket one with K&N filter, too bad I had to learn hard way but all the older stang owners were sure this was like all the others, it's not, old one was more of a ram air, this is true cold air, so buy a hand held at local tune place and get tuned, I paid 550 with our club discount then bought my JLT for 449.00 and retune for 150 so hope can save you some $$$$,
