But last time I got gas I didn't fill it. It stopped at 13.8 gallons (from damn near a dry tank) @ $40. So had I filled ALL the way up I am positive I would have made it to at least 320. EJ22T. Bad compression on the front two cylinders. 6-8 psi of boost through an intercooler, 3" down pipe and an Apexi Power Intake filter that's literally 24k gold. Special D1 Immamura Edition
That puts me at 22.22mpg.
