ColdFusionS10

Hello! I have a 2010 3.5L FWD FSport, I'm wondering if anyone with the same car as me has purchased/installed the GForce performance chip, they are being sold for $69. I figured that performance chips like the GForce that are advertised all over google are cheap and a waste of money? I eventually will be putting in the Steeda CAI w/tune but in the meantime, what will these chips actually do? Any actual mpg/HP improvement ? I appreciate your time in advance, Thanks!
