In the city I get about 22mpg(have a heavy foot) on the highway I've seen upwards of 31mpg
A tune would increase torque and HP(numbers will vary depending on which tune you chose)
Premium package? Hell yes lol it's a much nicer place to be in:D
This might sound ridiculous, but does it sound ricey or like a Honda? In your honest opinion lol and those are great next mod choices! Bring those IATs down!
