this question was asked once before. I think to answer was that ford has a program built in the the computer so parents can control things such as radio, speed ect. not 100% sure tho

When I watch it a bubble pops up saying that speed is limited on the F450 and F550. I'm not sure but I would assume it would be something to do with the speed rating on the tires.

So now the F450+ has 2 strikes: no more 19.5's and a speed limiter! All they need now is an astronomical price tag and they won't sell any.

I am pretty sure that is set by the my key ford offers as an option and not a factory setting.

It is a factory setting on the 450+ trucks, according to the Ford guys. At least that is what we were told, I was standing next to the guy when he shot that video at the press release.

I love the dash and it looks very nice, but things are going to far with limitations.

I would imagine that the dealer would de-limit the truck for you.

I have an 08 F450 6.4L and it has a limiter of 84 mph.... I think its because they have the same programming as the Chassis cab and as a "work" truck, a chassis cab "shouldnt" be going that fast in a commercial situation, so they limit it. Also, it is probably to prolong the life of the engine for commercial applications.
Its sort of the same principle as De-rating the hp and Tq ratings on manual trans and Autos with 4.88 gears.... Its to prolong the engine and drivetrain.

I dont think the dealer would remove the limiter, but....
