I would like to know which tuner I should order for improved fuel mileage. I am not adding any other aftermarket accessories but need better fuel mileage...thanks

U7164 is the ticket.

I got the u7164 and downloaded the 9r11 and it really helped the turbo lag. I havent checked the fuel mileage yet but the drivability is better by far...thanks for the advice
