I'm not sure if this the best place to post this one, but here goes...
I have an 02 excursion that only gets about 10 to 11 mpg. I had heard that a power chip can sometimes improve mileage, as well as intake and exhaust.
Obviously I started with the chip, because who doesn't want more horsepower? I went with the Edge Evolution and have loved it. Fuel mileage is the same, however.
Got around to installing a cold air intake this weekend and I hope it'll improve a little, but shouldn't I be getting more like 13 to 16 mpg out of the stock motor?
Any ideas as to why my truck is SO thirsty? Oh, I almost forgot, I replaced the fuel filter about six months after the chip, also with no change in mpg.
