Upgrading Intake and dme tune. 323 to 325

Hello everyone, I am currently working on changing my BMW 323i e90 2010.
Thanks to another forum, I've figured out how to add the second disa valve to my stage 2, But I'm clueless about the tuning swap to a 325. It's an msv80.0 if anyone can help me during this process, that would be great.

I will keep the post updated as I do the installation etc...

Thanks in advance to anyone who helps out.

I've tried looking for information, unsure if I'm just blind or if I can't find anything on what file is from a 325 that can be used in my 323 based on the information about my car.
The number on the physical label is 7609656. The engine is N52B25AE. The last 7 Digits of Vin are NM63719.

Looking through the database, I don't see any custom tunes for the 323<325 or 330 conversion.

Do you add a three stage manifold? I can probably find a 330 file that works for you?

Thanks for getting back to me. Today I pulled my intake off, cut out the hole for the second disa valve, and installed it. All runs well, but I kept the original intake and just added the disa.
