This is more of a hey this is a danger kinda thing. If you have an Ecoboost v6. I have noticed that sometimes when you have to accelerate very quickly the vehicle takes up to 5 seconds to respond and give you any power. I assume that the computer is spinning up the twin turbos but those critical seconds can cause a serious accident. I have on a few occasions almost got ran over because the truck decided to take its time giving me power to get out of the way. Its like for those few seconds you have NO power.
