I've just installed a cobb intake on my '16 FiST along with an AP. Already had a 3" MBRP catback, so I've been running it on the stage 2 OTS map, which Cobb's website says will work with my setup. Since the intake was installed I have noticed my Mishimoto catch can filling more quickly and with gassy oil. I even cleaned out the whole can & filter to be sure the filter wasn't causing this. Should this be expected with my setup? Should I go back to a stage 1 map instead? As for the intake , I love it. sharper throttle response, more torquey, and a great sound. It's not so loud that the intake and blow off are distracting while driving, but when I put my foot down a bit more it is fantastic.
