Me too. But, after our 1326.6 mile, 86.005 gallons of gas trip to and from California, using the homemade CAI and Bill's custom "economy" (non-towing) tune, I can report that I averaged 15.425 MPG for the entire trip. And, I was fighting a headwind for the trip into California. On the way back, the air was calm (half the wind generators in Palm Springs were shut down).
What makes this number significant though, is that before this, I've only seen 15.5 MPG in the 55-60 mph range in calm winds. Any speed faster brought my mileage down into the 14 MPG range. On this trip, we had five people in the truck, it was full of luggage, toys and food, and I was operating in the 70-75 mph range.
So, was this a result of Bill's outstanding tune, my CAI mod or perhaps a bit of both? I really had not had a chance to check this tune on a long trip before this, so I don't have a good base point for comparison.
All I know is, the truck's running better than ever!
