Due to a lovely van driver crashing my parked car through a garden well, I have a Cobb Tuner for sale:
https://www.cobbtuning.com/products/accessport/bmw-n54-accessport-v3-ap3-bmw-001
Has stage 1 and stage 2 maps (stage 2 requiring downpipes). I think it can remap standard cars to around 390-400bhp I had mine up to 438bhp with catless downpipes and air filters.
Looking for around £500 (cost me over £700 with import taxes etc).
