I think berk does a good job at keeping the code off, I actually had berk HFC when I bought my car without knowing. Had the code come pop up one time and I cleared it and it never returned. When I went to buy HFC( because I never knew I had them on my car in the first place) I replaced them with Z1 brand and it threw a code within 15 minutes and would not go away without a tune. I later found out I had berks on my car when trying to sell what I thought was a stock cat lol
