Ok guys sorry I'm just seeing this thread. I have the GMPP cai on my 2016 which I bought directly from SHOPCHEVYPARTS.com for $374 shipped 2years ago. This product is made by GM performance division, and here's the sweet part, the ECU flash is included in the price of the part regardless of what you paid for it. there is a labor code that comes with each one for the dealership to charge the labor to. it's not up to them. that said the you aren't going to see much change in performance with the flash tune. a little better low end response and some more growl is about it. it does look good in the engine bay though! Now once you get a true tune(Overkill is the way to go btw) then you'll be smiling about the intake tune combo. dropped just over 1/2 a second in 1/4 mile times at Camarofest last year!
