I had DL8 mirrors and I ordered the upgrade kit through my dealer.I had it (mostly) installed today and it took two techs about 4 hours to do. Then I sat around the rest of the day waiting for some updated programming to make the heaters in the mirror work. I finally came home and they tell me that hopefully tomorrow they will get the updated software to make them work fully. I do have to say the mirrors look nice and are HUGE. It is going to take a little getting used to. It was also stupid expensive and I honestly can't believe I had to pay that much to get mirrors that the turn signals work in. I made my dealer do them just because I have under 10k miles on my truck and I wanted the warranty to carry over to these mirrors too. While I absolutely can't justify the amount of money they charge to do this upgrade, the mirrors seem like they are top quality. The glass is very clear and distortion free, the lower manual adjust mirror gives a great lower view and I feel like they really cover all areas behind me. So, if you have a bunch of money to blow, get this upgrade - I used the clip on mirrors for one season camping and I can't wait to finally feel safe pulling my camper again. I guess safety doesn't have a price, but this safety feature smarts a little.

I also used to run the "cheap" stuff in my truck and my truck hated it! It would stutter and "felt" like it was struggling to go when I needed it to go. Switching to 91 (the highest in Idaho without a specialty store) fixed the horrible stutter and go issues. I have a log of hand calculated mileage since mile 4 (when I bought my truck) and it did slightly improve when I switched. Based on how much better my truck felt like it was running I have never switched back. I have now recently added a BB Tune and that solved all the other issues. Made my tuck awesome, and I even found out that Justin can make my truck stay in V8 below 50mph and in gears 1-4 so that if I am on a flat back road doing 55mph it can go into V4 mode and I can enjoy a little better MPG. I had no clue that had that kind of control in the tune. Saves me from having to deal with the constant switching around town and I still get the benefit on back roads! I am with the OP in this one - may not have added "power" but definitely made my truck run better.
