It’s possible but from my experience it doesn’t work. I bought 325i because I didn’t want to pay for 330i parts which I was going to replace anyway (exhaust, brakes, diff). After flash with 330i software and 330i intake manifold car was running but with much less power. I had to go back to 325i software and had it modified by DS Motorsport in Germany.
