Hello, my current car is a 2017 BMW 440i Gran Coupe X-drive.

it is currently tuned on BM3 stage 2+ E50, I know I am basically at the limit of stock turbo and DI. I don't want to put any more money in it.

I was wondering what a decent upgrade would be, F80? G87 M2? ZL1? I have a budget of around 40-60k USD.

I want it to be able to actually notice a difference in the driving experience because honestly, my current car is quite fast, Manual preferred except for an F80.

Please give me feedback, looking for some help. Thanks
