Car feels like running on 3 cylinders
The car was put into winter storage in driveable condition (i would not go so far and name it tuned) last fall.
I started the car after winter storage today, warmed it up and went to drive with AutoTune,
approximately after 10 minutes of driving I saved Autotune changes to the MS
and the car started to feel like running on 3 cylinders.
Return to the last fall restore point did not make a difference.
Could someone experienced take a look at the logs and tune please?
Base tune from Reverant, injector parameters changed and 2-3 Autune sessions last fall.
MSM, MS Labs MS2E, 640cc Mustang GT500 injectors, GM IAT, MBC

If it's a heat induced failure check the cam angle sensor. Those are a known failure point and can lead to misfire-issues. Ask me how I know.
If you must know, I found out when stuck on the george washington bridge during rush hour when I was taking my GF home to meet my parents for the first time. It was the third breakdown that day and every time it was a weird misfire issue that went away after the hood was propped up and the car sat for a 10 minutes and cooled down.
Edit: I haven't looked at the logs so maybe this is something that would have shown up there.

Thank you, Gentlemen
I see "lost sync count" is zero in my log, so most likely it is COP failure
But may be someone take a look into the log.
I am still the beginner and can miss something important.

I have new Cam Position Sensor and Ignition Coils installed (original Mazda parts from dealership).
Also checked spark plugs and the gaps - looks healthy.
Nothing is changed - as soon as car fully warmed up it feels like running on 3 cylinders, sounds like Subaru, AFR is greater than 15.
I spent almost $400 on the parts :(

(tune and setup in the first post)
I would pay for it, if nobody wants do it for free.
Is is starting from 400 seconds on the log

why would you spend $400 on a cam sensor and coils when you did no diagnostics to confirm either was bad?
stop assuming ****. you literally have an output test mode in your firmware that you can use ti fire your coils and spark plugs to see if they (or the ms wiring) is bad... your logs already confirmed your crank/cam sensors were fine. you cray cray.
next time you log, as soons as you feel the issue, press the spacebar. nothing in that last log indicates any issue...
