I just bought a Full Graves system with a PCV and I'm super stoked for it to arrive but I just had one concern. Jason at Graves said he was gonna map the PCV for the exhaust and I asked him, "Is gonna matter if I decide to install a aftermarket high-flow airfilter in the future" and he said "No". Now this has me curious... How on Earth would this not matter? Isn't the PCV controlling your fuel input? If I suddenly start flowing more air aren't I going to have to re-map the PCV for the additional airflow? Please gimme some insight on this!! Thanks forum.
