like 11.0 rich, or like 9.0 rich? Becasue one would be shooting out a little black smoke, and smell like fuel with catless exhaust. the other is washing cylinder walls, can causing severe damage.
I still cant see how Mitsu, puts a factory car out, that has to pass emissions, and get decent EPA rated mileage… yet its pig shit rich? EVEN after effectively LEANING out the car, but de-restricting the exhaust, de-restricting the intake… ie huffing in more air.
its completely backwards in my book. fuck if thats the case and this car gets 20mpg now, leaned out and tuned it better get 30mpg!
Also are we talking rich, under boost, or under vac and light loads? two major differences.
