Hyper flashing can be solved by changing the flasher relay (assuming it is replaceable). On some (most ?) newer Ford vehicles, the flashing is controlled by the BCM/"Smart Junction Box"/or whatever they call it these days !
A resistor kit defeats the whole purpose of switching to LED in order to reduce the current.
EDIT : This bulletin applies SPECIFICALLY to 2008MY Super Duty F-Series. It states that the flashing rate CAN BE ADJUSTED by modifying parameters inside the Smart Power Distribution unction Box processors.
I am not sure when this happened to E-Series.
I don't think most of us switch to LED to save current, we switch for the brighter, faster acting properties and perhaps a more modern look.
As you know, the minimal current involved of a bulb or resistor is inconsequential to the operation of the vehicle or its fuel efficiency.
