Yes they severely mess with the speedo and odometer. I went to a couple ford dealerships to see what it would take to flash the truck to correct that. The flash will run between $100-120 and none of them guaranteed it would be really accurate because the diameter difference was so different from stock to 35s. Just a heads up although you've got way more electronics than me so it might be possible on the second gen. I've relearned what all the speeds on my speedometer actually are using an app on my phone and just know that I can got to about 240 on the odometer before I need to fill up again. No more accurate mpg calculation though
