I have one. However, in my experience, it takes a bit to adjust. I have 34.5” tires and after install, I was about 6mph over at 75mph. Now After adjustment, I’m 2-3mph slow at 75. It works, if you find the right tire dimensions. Download a GPS speed tracking app that’s reputable, then start your calibration journey.

I was looking into this as well. But I want to know if it counts as a "tune" on your ECU and if you could be denied warranty work because of it

Not for me it wasn't. It works just fine once you get it adjusted correctly. But just choosing the tire size did not work. I went to a 33.5" tire from the OE 32" and the correct setting on the calibrator was 31.5" IIRC.

I think wheel options (rotational mass) has more to do with adjustment than the tire dimensions. I still recommend the product and it’ll likely save you some speeding tickets in my opinion.

The 35's aren't really 35's and once you put them on the truck the "rolling" diameter is even smaller. You need to know the revolutions per mile from the tire manufacturer and from that you can calculate the true tire size
