After discussing the issue with Seb at SpecialtyZ, he recommended I remove the CAI and replace it with the OEM set up and get K&N drop in filters since I'm getting a tune anyway and with the mods I have the horsepower loss is minimal and the vehicle will perform better. A very expensive lesson for me. As the saying goes "keep it simple...stupid!" Got Z1 silicone post-MAF intake hose on the way as well. This setup has been suggested by many on the forum.
