Hello i have buyed tuned car (with bad turbo) and it ate its new turbo in 15000km because of tune. I would like to revert back to original /factory tune.
I found file that is same sw /hw version as my. Compared them in winols only minor differences (the tune).

If i flash this file to my car will i also change my vin, odo, immobiliser, and other not tune related date?

Thanks for response in forward.

Why not channing this minimal differcenes , flash an you got ori ... based on ori file.
Best option.

Sorry i can not understand you.

compare both and transfer differences to file you have read from car
