    I had to fix some shit in the logs (you need to log Accel Pedal Position) but honestly both tunes are full of knock and look bad.
    I have no idea why cobb would release a "stage 1" map that was running lower boost and timing other than to reduce the knock you're getting (which it does), but either way, get a protune.

    Seriously.

    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!

    When I go the pump I always look at the total cost of the last guy who pumped and divide by the gallons in effort to try to find a line that has 91 in it. Otherwise you could be pumping a gallon of 87 in... just something to think about.

    Do you have E85 near you? You can put a gallon or 2 in to help suppress knock if you think the problem is the fuel.

    Lifehack: Fill up with 91 but pay for 87.
