Welcome!

Mileage is always a touchy subject. Bottom line, driver is the number 1 cause of bad or good mileage. Keep the tires properly inflated, if not SLIGHTLY over inflated, for best mileage. Also, an Exhaust will help out quite a bit. Don't bother messing with the intake. Its plenty good enough.
