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!

So far on our trip to Florida I am running the canned level 2 tune and the Gryphon is reporting 17.3 MPG! Last fill-up I did the math and it came out to 17.2, so I am happy. That is with 3 people, 1 dog, and truck full of luggage going 75 MPH.
