Well, were back on the MPG topic, and im getting a AWESOME 13.7, ive changed the fuel filter, pcv valve, reset the PCM, done everything except plugs n wires,BTW i have an open cone intake, so Boosten and I were talking, could it be my spectre filter ? but would a filter REALLY make a 5 MPG difference? has anyone switched between these 2 before ? I need help im out of ideas.
