N54 135i ignition codes after turner coils? Please help bms?

Hello everyone so i picked up a 2000 135i 6mt with 104k miles on it.

Previous owner was a kid who didnt maintain it luckily he only had it for 20k miles lol. Either way i got his problems.

Anyways heres what ive done so far

Removed and reinstalled chargepipe due to 30ff code. Found missing o ring in hks bov and bov was just spinning. . Installed and fitted it tight and 30ff gone.

New oil temp/level sensor since was throwing fault code for sensor. Code gone now

Misfire cyl 3 and 4... pulled plugs they where burnt to a crisp. I found pooled oil in 3 and 5 so valve cover will be next. and i Installed 2 step colder spark plugs and turner performance coils as well as cleaned out oil pools. Car cranked up nicely misifred rough as it burnt the oil for in spark plug banks for 10 mins and then cleared codes and Misfires are gone no more codes came back after a 5 min of driving.

Heres the new issue after driving around for 5 min and testing everything i parked checked codes all was good then went one more lap around the block and i got a whole set of ignition codes

2E78 normal 2step nls? Idk

2e1D ignition
2e1B ignition
2e19 ignition
2e18 ignition
2e1c ignition
2e1a ignition

6 ignition codes 6 new coils is this the cause? Is my tune setting need to be changed?

Car has

Jb4 map 1
Mhd idk what setting i have to buy the license still but def has burbles on max. Hate that shit
Vrsf chargepipe + hks bov
Vrsf fmic
Vrsf ca****s dp
Cts dci

New turner coil packs
New ngk 2 step colder plugs
Fresh liquimoly oil and filter.

Heres screenshots of codes and log when they showed up. Car pulled fine no misfire or shaking Was only hitting 8psi of boost because car wasnt fully warm so i believe jb4 was off still. But yea only gave it quick test drive didnt go crazy on it . Hit a small pull to 6k and let off . Got back to driveway scanned and found them.
