I’m not overly knowledgeable on the X2 but I’m assuming it’s the B48 engine? If so a downpipe, intake and a tune like a bootmod or jb4 should get you pretty close to 300hp. The main issue is that it’s already pretty heavily tuned from the factory since there isn’t really any major changes from a 20i to a 28i, if you want anything more you’d need to get an X2 M35i or probably just get something with the B58.
