Thinking of Removing Air Dam

I took mine off my 2015 silverado and I love the look! As far as loss of mpg you will definitely experience it but if your worried about it trade in the truck and get a Prius

I was going to remove it but decided to trim it. I really like the look of it trimmed vs removed.

Mine is off cause it got chewed up. Will get another one and see how long it last. I drive mainly old country roads. Not notice mpg difference.

I took mine off right away so that I wouldn't know what the loss would be!

That's a sore subject. It's a 2014. At 103,000 a lifter on number 7 rotated in its bore and ate a chunk out of the cam. Of course it was 3k miles out of warranty. Luckily I have a good dealer and they got GM to eat half the cost but I was still out $3,800 bucks. I am going to run it until the motor warranty that came with the new long block runs out (203,000) and this truck is history. That should be sometime around January. I think I am going to a 3/4 ton diesel next.

Other than that issue it's been a good truck. It spends quite a bit of time idling and at interstate speed with no real issues other than a total motor meltdown.

I can say definitively that all the catch can stuff is just hoopla. At 103,000 miles the valves looked pristine and the head looked almost show room new. I got to see all of them first hand.

Was the lifter that rotated an AFM lifter?

No it was a traditional lifter. That was a surprise I knew it would be one of the AFM liters but I saw it with my own eyes.
