Back to the matter at hand. The re-gearing makes a huge difference in how any vehicle accelerates and gave examples of that above. If you don't want to believe that or don't want to take my word for it all you need to do is visit your local dealership. Test drive two of the same vehicle with the same engine and different gearing. You will see a difference on opposite ends of the spectrum. A 3.15 and 3.31 car may not be discernible from one another, but a 3.31 vs. a 3.73 car will be. 3.31 vs. 4.30 in the trucks will be huge. While it's expensive to re-gear, especially if you have a 4-wheel drive its probably the most effective thing you can do short of a supercharger or turbocharger. Not every engine necessarily benefits that much from dropping the cats, replacing the manifolds and changing the exhaust. It all depends on what's there to begin with. I am not sure what the exhaust of the 6.2L trucks looks like as I've never crawled under one that wasn't a diesel. While tuning has a limited effect on most gas engines, I've heard that it does indeed do wonders for the 6.2L.
Also I'm all for customizing trucks however anyone would like to. I'm custom tuned and some exhaust work and imo it makes the truck fun to drive. Crawl under a longbox crew cab 6.2 sometime. You'll find cats, two separate resonators, and a muffler. That's a whole lotta exhaust.

Count me among those happy with 5 Star. Contact them, tell them what you have & what you'd like it to do. They always got back to me promptly when I had questions.
Got a 2011-2016 6.2L V8 Super Duty? - 5 Star Tuning
Contrary to what Hoss might think, I also did it for an economy tune. But the 87 octane daily tow is nice for the handful of times I do tow every year. A lower gear wasn't in the cards for me because as he says, I don't tow heavy and often. Also contrary to what he says, you'll see me at the funeral home as guest of honor before you'll see a Subaru in my driveway.
As I've posted before, my only complaint is with SCT, not 5 Star. All my devices are Mac. When the SCT needs updating I'll have to send it back or find someone with a Windows based computer.

Do you see any MPG improvements?

You really shouldn't see any MPG improvements from just a tune in an engine like this one. Responsiveness in shift points or the drive by wire throttle response, sure, even maybe timing adjustments. But mileage is only really going to improve with judicious use of that pedal on the right, restraining yourself from adding any heavy bumpers front or rear and winches and lifting it or putting on oversize tired and all that. Without some fundamental mechanical changes (not exhaust or a replacement intake tube or throttle spacer whatever else) actual fuel efficiency won't be impacted much, certainly nothing outside the margin of error associated with your gas pedal usage and cruising speeds. Even with the placebo effect tempting you to go easy, it would take a very long time for any such tune and tuner to pay for themselves in any tiny MPG increase.

It's hard to say at this point. I really haven't kept close track when driving locally without a trailer behind me. I sold the F450 bucket truck that I'd been towing the business trailer with and have been using the F250 for those duties now.
And I went to the dealer the other day for a TPMS issue so I went back to stock tune. They're waiting for a new BCM so I left it stock for now.

I got it tuned and it is definitely an improvement. I have the 86 octane performance tune on it now. I'll try the 91 performance on my next fuel up. I have the 86 octane daily tow tune for towing also. Apparently it is a good daily tune without towing and you get a double benefit with tow/haul mode when towing.
The 86 performance is much firmer in the shifts and the throttle response is better. It doesn't magically make it like a diesel in the lower RPMs, but it is a good compromise for people who don't want the expense of a diesel, especially if it's a daily non towing driver. Happy with this option.
Put Jimmie Jammers on all 4 doors and a lock delete on the driver door today too. These trucks are stolen daily around here.

I know that with my 5 Star/SCT device, different tire pressures can be set for the TPMS. I have no idea if you can shut it off. My truck was in the shop 2 days ago for a "tire pressure monitor sensor fault". They said their diagnostic tools couldn't even find a sensor and they had to break down a tire to make sure I had them. I've had this truck from new and the sensors have not been removed. I only had a bigger size tire put on the truck.
So their solution is to order a new BCM. I'm waiting for that to arrive. Personally, I think they're throwing stuff at the wall to see what sticks.

I don't think you'll lose mileage unless maybe you go with high performance tune of some sort. Although I haven't been a mileage maven, I do notice the better shifts and performance when towing as others have mentioned.

I switched my wheels and tires off a 2016 F250 to get rid of the "Chrome Clad" plastic and go with aluminum that my cousin had. I didn't even snap that he didn't have the TPMS. That is one option I wish my truck didn't have. Its no big deal to clear the alarm every time I start the truck, but it would be nice to disable the function. I emailed 5Star to ask if they can.

Your choice, but after my experience, I will opt for the sensors.

Looks like you are right, though. http://www.nhtsa.gov/cars/rules/ruli...nalrule.6.html
I do not recommend disabling it or running with TPMS. I'm not a fan of the 'nanny state' stuff either, but I can tell you that during the brief period I ran a set of take off wheels without tpms I picked up something and did not realize it until I 'felt' it. As a result the tire was ruined. It is cheaper to have new sensors installed than it is for a new tire given you need to spend 'time' changing the flat, ordering the new tire, and having it installed. Then, I suspect, the tire place has to install a sensor so you are stuck paying for new sensors AND a new tire.

Of course my assumption is based on your cousin being honest and that he did NOT remove the sensors to use in his new tires. Not saying he did, but I got burned by a person with little integrity on a 'take-off' tire purchase.
The valve stems are a dead give-away; I did not know this when I purchased, but learned it later.

If they are factory wheels that are used with vehicles that come with TPMS then they should at least be compatible with the system even if you have to purchase the sensors after the fact. I would just get the sensors rather than disable the system.
