So, as a "new to me" owner of a 2006 LR3 with 162k miles, I'm happy to report I think I resolved the performance issues I was having, part of it might have been MAF related. I know it is a heavy vehicle, but with a 4.4L engine, I was expecting a bit more power while on the highway in overdrive encountering some inclines. Previously, the engine just felt bogged down having to downshift to climb the slightest of inclines.
So, I did a full Sea Foam cleaning... gas treatment, oil treatment, and intake treatment. Ran for 500 miles, then changed oil/filter to Rotella T6 5W-40 synthetic, which I use in pretty much all my vehicles. Not knowing the previous service history, I installed a brand new set of plugs too. Next, the previous owner had installed an aftermarket Delphi MAF sensor. While researching MAFs, I saw this product from JET Performance:
I was doubtful... they claim they have improved electronics with enhanced MAF tables that help improve performance. Hmmm.

At $212, about 2x the cost of a normal MAF, I wasn't that interested. But then I found a new one on amazon for $99. Decided to give it a shot. It appears to work great... my butt dyno feels a difference from the Delphi MAF, but it might be placebo effect or improvements from the cleaning and new plugs...
Anyway, my LR3 is running much better now. on country road 65mph highway driving, MPG computer says I'm averaging 19MPG, and that is with a roof rack installed. When I first bought the vehicle, it was reading 11.
So, I'm a happy camper for now.

Thats not a slight crack, just suck into a straw with a small hole. Does not take much!
The only MAF that should be used is OEM/Denso. Dephi probably fine. Those others are just marketing. There are a TON of fake MAFs out there, always buy from a legit source. Denso MAFs are about $70USD at the Toyota dealer.
Also that's the wrong oil, 40 weight is too heavy. But if you are in a warm climate probably. not a huge deal, just don't use it in cold climates. With that said, Rotella T6 5W-40 is not good for the cats which on more cars is not a huge deal either, but the 4.4 is know to consume oil more than equivalent engines. Again, go with what is proven/recommended is best practice.
