I’m coming out of a heavily modified 392 Challenger making 671 rwhp.

I’m going to order a 2025 M240i xDrive. About 600 to the wheels will keep me at the same power to weight ratio I had before, only with AWD, which would be awesome.

Can I achieve that with a tune, intake and exhaust components, or would that require something more like a turbo pulley?

I want to also keep it reliable and with good road manners for long trips and such. Also, normal 93 octane pump gas. Thanks for any input!

You will need a bigger turbo

the ECU is also locked from the factory so you will need to take it out and ship it overseas to unlock it

I hear that every time BMW send an update it will wipe the new map. Not sure how true this is.
