Following was checked and verified:

125i and 130i and Euro X3 share 100% equal engine with only different ECU algorithm
128i might have (this is my guess) different intake manifold in the past (I don't know until when), but supposedly later is same as 125i/130i (again, pls. verify for yourself).
X3 makes 272 HP stock.
325i was re-tuned here (after ECU algorithmn cracked) to 272HP initially and to full 280 HP later. Same I expect for my 125i.
Guys do it here and in Germany, so no questions.
At your place, I don't know, but you can send your ECU to Germany and they will do it for you (it has sense when you get confirmation that your engine's manifold is same like Euro 125i). In Germany is costlier, but they do software tune deeper and without dealers being able to 'see it'.
Cracker's here did good job for tuning itself, but couldn't overcome system change identification, so if I go to dealer I just re-set to OEM SW data.
1800 Eur (minus VAT) is IMO best spent money on tuning N52 up to 270-280HP.
Next step would be intake/downpipe we hope to get from RR.
Together it would make car rocket fast, breathing much better and important much stronger on higher revs.
