It’s worth about 40whp according to BMS. It’s a decent increase although not as robust as a flash tune.
You also don’t need to remove the DME to flash it. A BMW performance shop should be able to access it by only removing a couple components and connect to it via harness. For most people, the problem is finding a shop that knows what they’re doing and have experience with this.

The install a JB4 in a M2C is going to be a pain the ass because of the tight squeeze, in the engine bay.
Plus, you have a manual, so you have to remove the rubber grommet on the firewall, to passthrough the OBD2 wire and plug, which in time, can develop a leak, as a result.
