agree, n51 wont make as much power as 330i N52, but 0.7 compression should be just 3-5hp/tq.
N52 came with secondary air injection as well, i think the other difference is with both main and secondary cat, it appears to be denser/havier according to online part catalog.

N51 with DISA enabled should be on par with 330i N52 255hp if you had intake and exhaust swapped out , but not as much as 328 N52 with 3stage and tune. you should be worry about that, its only few hp, not day and nite difference.
here is the dyno chart for you guys to reference.
car is with early beta version of ESS N51 tune and PI.
ESS tune dyno'd first and stock tune second at same time, so probably not much time for DME to adapt back to stock setting. I feel car probably can do about 220hp with PE and current revision of the tune, but yet to find time to confirm.

I have the n51 e90, what is this tune and how do i acquire it because it sounds like great fun. Currently i just replaced the stock air filter with an k&n one.
