Both codes are pointing to the wawa pedal, not the throttle body, so that's what I would check first.  Highly unusual for it to be that, but if there has been water intrusion of any kind, then it is quite possible.

P2122 - Throttle/Pedal Position Sensor/Switch D Circuit Low

Description:  This DTC sets when the accelerator pedal position 1 (APP1) is out of self-test range low. 
Possible Causes:  APP1 circuit open
APP1 circuit short to ground
Damaged APP sensor

Diagnostic Aids:  An APP1 or APP_D sensor PID reading may indicate a concern. 
Application   Key On Engine Off  Key On Engine Running  Continuous Memory 
All     GO to Pinpoint Test DK . 


P2127 - Throttle/Pedal Position Sensor/Switch E Circuit Low

Description:  This DTC sets when the accelerator pedal position 2 (APP2) is out of self-test range low. 
Possible Causes:  APP2 circuit open
APP2 circuit short to ground
Damaged APP sensor

Diagnostic Aids:  An APP2 or APP_E sensor PID reading may indicate a concern.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

I really hope this works for you.
Thanks man me too. Been doing alittle bit of reading. If its not the throttle pedal,  it could be a bad wiring harness or a bad pcm. Really hope its not either of those but i guess i will find out.

With the whacky OAR reading,  I am leaning to a harness issue or at the lower end of possibility a ECU causing it to adjust itself.  Have you pulled the harness off the ECU?   Z/SHOdded have seen corroded plugs before..

I have pulled the 2 main harnesses off the pcm and everything looks fine there. Nothings corroded

There should be 3 harnesses connectors!  For reference here is good link for ya. I think you Need to provide as-built-data. Z

Only 2 on mine unless im missing something

Pedal is on and codes are cleared. It does feel alot better and seems to be holding 6th alot longer before a downshift,  but im still not 100% if its fixed. Boost still looks to be the same, but i havent put my tune on to see if it increases. I want to run stock for alittle to see if codes return and if it starts acting up again.

SHOdded

Oh man!  Really hope the PCM is not bricked!  It should detect issues with the MAP sensors but ... are both identical on your F150?

Both MAP sensors identical or what are you asking?  So far no more codes after switching out the pedal and it does feel somewhat better, BUT i did put my pedal in my dads truck, and his still runs perfect. So is it just in my head that mine feels better maybe. I guess i need a few more days to see what it does.

SHOdded

yeah it might be a placebo effect ...  I was wondering if both are 2.5 bar sensors or if one is 2 the other is 3 like on the SHO.  If they are identical, swap them and see if you see a change in behavior.  That kind of thing.

Is the wastegate hose intact based on the pic below! 
I would not give up on this truck that easily IMHO! Z

Yeah, I mean, you can always contact Ford Customer Service and tell them that your truck has been misbehaving since this flash update was applied.  If they have something (engineering team), they can help you right away, or call on the engineering team to look into it.  This is a big deal, and they want their F150 customer base, as far as I can tell LOL.
