So one of my friends, got 2 codes on (p0328 & p2185) he had a custom tune with flex fuel & catless dp. He put the factory tune in with factory dp & still the codes are there. Could it possibly be the flex fuel kit?
I'm all for doing what you want with your property, but hey, I've seen countless articles here and in other forums where mods, especially tuning and hardware swaps have caused nothing but problems. maybe our cars are a little too sensitive to being modified? maybe we should simply stay stock and live without those issues? again, do what you want, but it just seems logical to me that with a car controlled mostly by chips that altering things will inevitably cause issues.
