this is of the utmost importance, because on monday im either ordering nistune or a rom tuned ecu

Well the short answer is no. It does calibrate most things but it will by no means have you tuned. Basicially it keeps your car with the ability to start and usually drive but it will need attention. You have to tune it still.
That shouldnt be a turn off though, that is actually whats good about it because you can end up with a fully custom tuned ecu and tune your ecu in the same manner as you tune a stand alone.
Pre tuned ecus are just about worthless honestly. They are a bunch of guess work and telling a company what injectors you have and what maf you have, well there is no way to actually make a good tune based off that information.
