You still average 20MPGs with AFM delete?

I get that same with mine. On the highway alone, I am getting 24 MPG

Tuned out AFM over 30K miles ago and my mpg improved by .2mpg. Last 30K mpg is 20.2. We live 40 miles away from our son that has the 2015 Yukon Denali who's house is at the same elevation as ours with lots of twisted & hills in-between (Oregon). He got 21.4mpg going from our house to his last visit so I check mine the next week curious with the cam swap effects and I got 27.2mpg avging 37mph.

With 1000 miles on the AFM cam delete setup I've had many 100+mph events, plenty of traffic time, many stop lights and a few running idles wihen I went into a store with my wife staying in the Yukon and my overall avg mpg is 20.5.

My driving style is get to operating speed as quick as possible (cheap thrills) then maintain speed but only use by brakes when absolutely necessary.

For what it's worth, here's a couple of resources I came across when I was trying to make the same decision. They both indicate that you'll get more reliability from the 2010-14 over 2015-2020. Obviously maintenance is key so I would probably rather have a 2016 that's been well taken care of over a 2014 that's been neglected.
