Well, not sure what instructions you saw. It is a pretty straight forward setup. Just did a mileage check this morning, 110 miles, main roads and freeway, it did 24.4 MPG. Can't wait to install the Morgan-Tec cold air system that Mike is building for it. I don't sell these, I don't get a kick back, don't have shares in the company. Just wasn't pleased with the mileage it got, espically with the price of gas these days, so thought I would give it a try. Hey, it works for me.
