Had my 2021 stinger gt1 for about 6 months now and i love it, so far got injen intakes, borla type s catback, jun bl secondary down pipe, and today i installed hks spark plugs gapped .024, jb4 tune and add w1 OCC. i used the hoses that came with can and i get a hissing sound from pcv side. I tried to tighten/loosen connection but sound still there, did soap method and no bubbles forming, is this normal?? Also i run 93 octane so map 2 would be best? Thank u guys in advance!
