I’m in Australia and own a 2009 323i e90

It has a n52b25 and I need some direction if I could please, I’ve looked under my bonnet and located my larger disa on the right side of the intake but on the inside I want the dremmel out the already there hole, screw in a smaller disa to the mount that’s already and plug it in to the cable that’s already there and give it a tune for the hope of some more power, I’m fairly confident in doing so and have read the thread on the bloke who managed to do it but I want to know if it’s any different in Aus will adding a smaller disa mess with my dme or will it be fine and will any small disa from an e90 work like can I get one shipped over from America and put it in even though they are in 3.0l over there (I think) will my 2.5l be fine?,

Any help super appreciated

Try to get the updated part number for your disa. You can look the number up on realoem.com. Don't buy aftermarket ones either. And no it definitely won't mess with your DME.
