[QUOTE="MRV99, post: 1710498, member: 53833"] I just did a IL to IA trip. It was only 300 each direction and we were driving from IL to IA at night so I had time to observe. Everyone was face deep in electronics and I was basically driving solo :birgits_tiredcoffee The route was 289 highway miles and 11 off highway. For those who care. 780 elevations start, 951 elevation destination. So I selected the "Measurements" on the Dash and scrolled to the second screen. This gave me the Boost/Vacuum readout. The road is pretty much flat but since I had 300 miles, I had plenty of variations to test. So what did I find, exactly what I knew, boost equals bad MPG... Yea we all knew that but how did boost relate to MPG AND speed. If I was cruise at 70mph, the boost bounced from Vacuum to 1-2 lbs and 16's was pretty easy. I would then set the cruise on 75 and the boost would stay pretty constant 2-3lbs with spikes to 4lbs... I saw pretty constant 15's. I then 80mph and I saw 4-7lbs of boost which the MPG dropped to low 14's. This was the drive out. I also did some gear lockout to try and remove boost to see if that would help with MPG. I did not really see much MPG change by driving in a lower gear, higher RPM and lower to no boost. On the way home, same highway, similar mileage changes. I did the same tests yet had similar results. We had a good tail wind so I was able to drive faster and saw lower boost numbers. I had a 2015 3.5 Lariat with 205/55/20's with a level and made this same trip same trip close to 20 previous times. The Lariat and the MPG was even worse like 80 was 12mpg. I chalked that up to the 6speed, E-rated tires and the level. I did adjusted the MPG counter on the dash, (other forums called it the "Lie-o-meter") by the figuring out the actually MPG and adjusting the computer(in the hidden screens) so my MPG is pretty dam close to what the actually numbers are. Yes speed kills MPG on these square chunks of heavy metal driving down the highway. [/QUOTE]
