I have a 21 Powerboost with 6 inch BDS lift and 35s with Fuel wheels. My speedometer is off about 3 MPH when set to 75 MPH, so I’m doing 78 MPH at that speed and RPMs are at 1900, if I back down and set cruise control at 73 MPH the RPMs are at 1800. Watch your turbo gauge at those speeds, it’s...

Just put Toyo ATIII 35x12.5x20 on my 21 Powerboost with 6 inch BDS lift. I don’t like these tires at all. Had Toyo ATII, same size, on my last F150 and they were awesome. These tires ride extremely rough, tons of vibration above 55mph on the pavement and much louder that the ATII’s I had on my...

I definitely didn't get this bad of MPG when I first purchased the truck. Are you and Snakebitten implying the MPG should get better over time? As stated before I am absolutely not a mechanic so any technical info is always appreciated.

So two days post software update. Takeaways- MPG has dropped significantly. I used to average 22-23 MPG with better gas mileage around town and lower MPG on highway. Average MPG the past two days is down to 18 MPG on the same routes I've driven with this truck for the past 8 months. Before...

Yes it did- did you see my post?

Good afternoon everyone. Took my 2021 Lariat Powerboost in this morning before 8am and dealer was done by 12:30pm. Here are the notes from the work order TSB# 22-2224. Reprogram the PCM and any other modules required by the software update and service procedure. (You can see the full notes on...

Heard back from dealer today-the update is an all day update (approximately 6 hours is what I was told??) . Dropping my truck off Monday morning before work. Hopefully will have an update late Monday or Tuesday

Not sure if for Canada but not an OTA update- they were hoping for OTA but looks like trip to the dealer

Good Afternoon everyone- a lot of you guys have reposted or replied to my posts over the past few months (thank you). I received a call from the lady handling my Lemon Law case at Ford this morning. The software that was scheduled for release in Mid May and again this past Monday was released...

The Ford engineer said they were hoping they could push this out over the air without having to bring people into the dealerships. They did not commit to that statement though, just that they were hopeful that the release would be done sometime in mid May

Finally had my day with official Ford Engineer that supports my local dealership. This was after multiple repair attempts and following my state’s Lemon Law process. Test drove truck with service manager and Ford engineer. Replicated shudder multiple times on a short 20 mile highway trip. Ford...

Mine gets worse the longer the drive . RPMs 2K-2.3K at highway speeds is where my shudder happens so I dont think its an "Under Power" issue. You seem to have more technical capabilities and knowledge than myself so I am watching and reading with intent to learn. I drive a lot, constantly on...

Wish they would have jumped on mine…..and helped

Amazing isn’t it. Ford engineers have figured out a way to make a truck with built in vibrations and shaking. Problem is they forgot to tell their customers in all their disclaimers and even forgot to tell their authorized repair dealerships….GIVE ME A BREAK. None of my other F150s or my old...

Truck update - finally synced up with the Service Manager last Monday 2/28/22 I brought my truck in, towed my small 17ft flats boat as requested. Took the Service Manager on a 10 mile round trip on the Interstate. He felt the shudder just as they had before. Notes on the work order from dealer...

Update on my truck 1. In a prior post I provided video of rough idling and truck shut off 1 week prior to my 4th repair attempt on transmission. Truck was taken to dealer they had it 3 days. They found stored codes for rough idle and Powerboost unavailable. The dealership didn’t repair or try...

FROM BAD TO WORSE TODAY Called the dealer and let them know my truck would be towed to them a week early with a new issue engine issue Received a call back from the Service Advisor stating (1) They could not provide a rental until the new issue is officially diagnosed (2) They are so far...

Truck being towed to dealer today. Started truck to drive to work this morning and the truck felt like it was running down a few cylinders, engine was really sputtering, it eventually shut off and gave the message "Stop Safely Now". (See video below it eventually just shuts down) Truck was...
