Should I be worried?
So after I did ZZP stage 3 I started getting awesome gas milage. Along with a p0171 (which I also had before since I did the air box mod). The reason I'm questioning my gas mileage is could my car be running super lean? I mean I just drove an hour home in 50% stop and go traffic and my ECON went up a point! Its at 36.7 MPG avg. I have a AFR gauge budgeted in a few months but this might make me get it quicker. Its ZZP canned tune.
Sorry, its a stupid question...
