I'm currently using the best gas in the area which I guess is still shit because of california. I'll be getting a tune in 3 months when I have a job again after I finish my first year of college. Usually, in Sacramento the car doesn't knock at all. But in Santa Clara, where I am right now, the car is more knock happy. I'll be getting the HPFP in the spring when I do the VVT so yea. Thanks all for your help!
