Deleting AC is an easy solution where I live (Seattle) but for those in the overheated zones of the US I expect savings would be offset somewhat by increased laundry bills.
Also, I asume you are keeping windows closed. I don't frequent these page and I'm sure this has been covered over and again but isn't AC vs open windows a wash when at hwy speeds?

After getting LRR tires, I finally doubled my EPA mileage too! Automatics are tough but it can be done.

50 MPG is quite an accomplishment, but at what price?
50 psi seems very high, must be well above the manufacturers recommendation, this has to affect traction, stopping and handling. What potential risk does this have on both you and other drivers around you?
Advancing the timing and running lean while disabling the knock sensor... This sounds like a recipe for a ruined engine, what's the cost of yet another engine?

I live in Houston and still have the AC hooked up and will keep it that way. If it is just me in the car i wont use it and crack the window and 2-3 inches.

Actually referring to the OP's list of mods.
Also, the sidewall max pressure and the manu's recommended pressure are not the same. The sidewall max pressure indicates what the max pressure that is safe for the tire, the manu recommended pressure is what's safe for operating the car.

Lot's of questions to answer

But first, Congrats Jethro, you will be passing me in no time at all!

I keep my windows about 2" down and just sweat it out in 100 degree temps. Below 90 is just fine. In 80 degree temps, I only keep one window cracked and 70 and below I keep em up.

Yes, LRR tires are key because of no EOC. It is possible with autos, just not as easy as manuals.

50mpg has come at a great price. I save over $1000 a year in fuel costs. The LRR tires I have handled much worse at 32psi, like a jelly donut on a toothpick. These tires, by nature of being very LRR, handle much different than "normal" tires with reduced traction and handling, therefore I drive it appropriatly. I'd like to believe driving the way I do is much safer than chatting on my phone while passing on the shoulder Point is, risk is determined mostly by your actions, not your equipment because we are opperating well bellow the maximum limits. Tire psi is a much debated subject, I stop commenting by saying it is best to expirement for yourself, rather than just reading what the net has to say. I have not arrived at this pressure by accident

Advanced timing, while running lean without a knock sensor....well, you just don't understand it yet. It makes sence when you begin to study it. I have not done this without a good understanding of the physics and risks. I've got over 25K on the motor while running lean with no damage. This motor cost me $200, it's an Escort, they are dirt cheap. There is not much info on running lean for mpg. Most just understand that lean mixtures burn up motors, but this is only under a significant load.

Don't mod your car in a way you are not comfortable with! I'm comfortable with what I have done and capable of dealing with the risk and potential outcomes.

I'm a bit crazy, maybe you figured that out, thus the crazy stuff I say

well want another 60 mpg tank but just a 58mpg. but I did increase my total average over EPA and now up too 112.3% that puts me real close too the 8th and 7th place people.
