Before,the mod my gauges avg stayed at 22.8 mpg, and that coincided with mileage and the pump pretty close within .2 so now the gauge avg is 25.4. Maybe a placebo effect, am I driving better? Idk. If this is the case how do we fool the o2 and maf? I also modified my airbox, cut a slot in the resonator part allowing air to come under my hood straight into the airbox, pre filter of course
