Gas Mileage Changes After Cam Phaser Recall Performed

[Badgertits]

My trucks got 82k miles. Run 93 octane. Been running a Gearhead performance tune for 81k miles. I get 15mpg overall. Doesn’t matter what I do- mpg around town ain’t great but doesn’t seem to be much worse than 15, only way I get better than that is cruise control highway below 73, as soon as I crest 72/73 anything better than 16-17mpg TOPS is impossible. I don’t care to nor need to see any “proof” otherwise.

I live in MA. In winter I will lose 1mpg give or take, it’s hard to know exactly as I tend to remote start more
Often in winter
