A very strange behavior after battery got empty

Hi guys,
I have a 14 GT Auto transmission running 93R tune by Bama.
A very strange thing happens to me today and I would like to have your help.
My battery went empty (not sure why) and then I recharged it using cables connected my brother's battery car.
I start driving right after I car ignited and at first I felt a very big knock when I changed gears from Neutral to Drive and also to reverse. Something very unusual.
In addition, while driving, I felt like my car is having very high RPM but car is barely moving. Something like RPM go to 3 but my car hasn't even started to move! When I got to 40-50 MPH RPM refused to go down and it felt like the gear is not changing to 4th and 5th.
I decided to pull over, turned off my car completely and started again, only after that I think my car went back to normal: gear and RPM.

What's the explanation for this issue? Is it related to the BAMA tune?

Thanks!!

I believe this is why Bama says NOT to do idle re-learn. The first bit after battery disconnect can be angry.

So is this normal?
How should get back to normal, as before battery went empty?

Thanks

drive it for a while....you may want to reload tune but if it's working now I would let it be. Batteries do not like going dead, it may not last now but see. Did you leave anything plugged into the power ports or something else that may have drained the battery or not run it for 2 months? The ports do not shut off ever...

Not sure why your battery went dead? This right here is why.

If the issue with your car's drivability comes up again, reload your tune.

Something similar happened to me after I took the battery out to work on my car, it was out a good 10 hours, and then as soon as I put it back in, I loaded up a new tune, and my rpms have been a little high, so it may be a similar problem. Normally like they said normally the tune will sort its self out after a while as your ecu relearns it, but if it keeps having problems maybe datalog and request another tune to see if it helps?
