2007 F250 Speed Limiter

This might be a stupid question, but exactly how does the speed limiter work in a 6.0 Powerstroke? Does it just shut the fuel off?

Yep! Shuts off the fuel pump and sets a code after a certain speed/load/rpm area.

Could that end up harming the injectors if it happens more than once?

Nope, other safeguards are there too.

why would it hit the speed/rpm limiter multiple times?

i mean on seperate occasions. There have been 2 or 3 different times when i didnt realize how fast i was going and the limiter kicked in.

Sounds about right- I think the official number is 92 mph. There's actually a good reason for that- the tires aren't speed rated, and a blowout in a 7,000 lb brick with zero handling capabilties could be more than a little dangerous. That includes you and anyone else in your path.
