The Z06 is not a CAI from the factory, be careful propping open your shroud which can cause maf turbulence. You will see your fuel trims bouncing around at idle and feel it at a steady speed. Will feel like an older car with a bad EGR valve.
Use something like a Halltech bee hive and prop your shroud in a way you can adjust it if you have turbulence. Do a search online and you will see some pics.
Just remember, you can not tune out maf turbulence.
