I have had this issue on every Ecoboost Ford I've owned. Sucks when you call on the blessed mother of acceleration and she ain't there. Call it turbo lag, dead pedal, whatever it is, it's annoying and can be dangerous. It is as if the the truck doesn't know what to do when the pedal is...
I used up my Fordpass points yesterday on an oil change and Bronco Bluetooth speaker. I’ll do mine oil changes going forward, I‘ll use Mobile 1 and an oem oil filter.
I did this to the back half of my folks 06 Focus, under the back seat, under the wheel well trim panels and everything in the trunk, it made a difference. I also added a hood liner. Don't plan on doing my Bronco anytime soon though.
