Maybe this...

Seems like MCU 54 fixed my random flashing of the SYNC screen as well as fixing the backup camera freezing before it was fully booted up

Do you have Forscan or another scan tool? I believe it can show what the BMS thinks the SOC is

I'd also suggest looking at your battery voltage after a full charge, and then again when it's not working. Sounds like you may have a drain on it for it to stop working after sitting for a day or two

According to google: Punch pass code then 5/6 and the tailgate would pop

If it follows the same as the non-ho I think it was up to 70k miles it was covered 100%, then drops to 66% until 80k and then 33% to 90k. I could be wrong, that's just what I seem to remember the TSB stating

If you have a battery tender or similar charger, try to charge the battery. The Ford BMS system doesn't fully charge your battery to prolong it's life, but when you make a lot of short trips or don't drive it often, you can have get a weak battery that will cause similar issues

You cannot make any as-built changes with the IOS version, you will need the Windows version. Also note that disabling the fake engine noise will also disable the ANC (Active Noise Cancellation). Fake engine noise disable ACM 727-01-01 xxxx x0xx xxxx DSP 783-01-01 Exxx xxxx <---2018...

Thanks for posting this, although it seems excessive and I'm not sure where many techs or even owners will have the place to run thru 7 cycles in a row. Is this just suggested, or is there a PID to show learning has completed?

Do you have a tune by any chance? Some users have had to remove their tune before it showed the VDM. I think it has been mainly MPT users so far

Here is the thread I mentioned before.. https://www.f150forum.com/f118/upgrade-sync-3-v3-0-v3-4-instructions-458828/index104/#post6945872

I believe that was the one having issues. F150forum has a Sync 3.0 to 3.4 thread where some users have mentioned a similar issue. I think there is a newer version in that thread you can try

What version of SYNC are you using? I believe one of the recent versions had a Sirius bug. Are you up to date on 21020?

I believe if you hold power and seek forward together for 5-10 seconds it will reboot SYNC

I wonder if it has anything to do with the Lightning having the most HP/TQ of any *current* truck... Maybe that's why they are releasing it before they announce the power of the Gen 3??

Most likely the NA 20 maps.. might take a few days to download all the files

Have you tried loosing the spring and shackle bolts again on the drivers side at ride height and then retorquing after cycling?

The drivers side wastegate looks open in your picture. Did you say it won't budge or were you able to get it to close and it didn't change anything. I listed to some of your videos, I'd see if you can get someone to rev it for you and try to pinpoint where the noise is coming from

Also as someone else previously mentioned, check your air filter and make sure you don't have anything blocking air entering it or clogging the filter

I would think it would still make some boost, but I can't say for sure. It wouldn't really "leak" though. I also think you would be getting wastegate codes. I'd go back over the charge pipes again and try to examine the intercooler for damage. I'm sure other's will chime in with some suggestions...

I believe towards bumper is closed:

Yes, I'm not sure if Turbo Wastegate Percentage is a valid parameter in your logging software but it shows 0 across the board I believe you would get a wastegate code if they were having issues, but you should be able to test and make sure the wastegate arm moves freely
