Just to let you know, im not the best tunner, i know some, but not nearly as much as you guys do, but anyway, i have a greddy exhaust, injen intake filter, and H&R lowering springs on my car with some other exterior modifications, but lately my car has been sucking gas a little more than it used to, what do you think could be the problem, does it have anything to do with the injen intake filter?????????????? should i clean the filter or something, because i have had the car for 2 years now, and all of the sudden it starts sucking more gas than it should????????????
