Great information on the Banks Power Pac. We just bought a 1999 Mountain Aire with an F53 V10. Our calculated mileage coming back from FL for 1,500 miles was 5.5mpg but we had some problems with the Mass Air Flow Sensor. We just ordered the Banks Ram Air Intake and will try that first. Can't wait to get it installed. Next year we will try the whole exhaust and chip upgrade kit. I just got back from a 200 mile trip running at 58 but haven't filled up yet to check the mileage.
