I haven't tracked yet and I'm not sure if I'm going to use this, atleast not right away. I have a r32 being turboed and set up for the track ( long story) and that's also why I said it depends how you drive, if your drive normal following the speed limit you'll get better gas milage lol. But I use the car for more traveling then anything so it does it's purpose well, I'm sure once I get it track ready I'll Cry at how fast I go through gas :.(
