Hey folks, anyone here in Australia (particularly eastern side.. Victoria) who have done performance tuning to their X3 m40i's? If so, what did you do to it? Is it worth it?

JB+, worth it for a easy 40hp

I'd recommend BM3.

I think anywhere you can get BM3, MHD and MG Flasher.

I have been torn between MHD or MG Flasher and a more traditional take it to a garage for a remap.

The thing with the app based remaps is that there are now loads and loads of people using them so I guess all are 'ok'.

So far I have done nothing ... but am tempted

I have been running a RaceChip GTS Black for over a year now on my 2019 build. Promises +76HP & +100Nm (from 354HP & 500Nm stock) but not had it on a dyno to verify. However, the best 0-62mph time from my RaceBox dropped to 4.11s on a slight incline with cold(ish) tyres so the engine definitely has a lot more to give.

Downpipe, intake, huge fuel pump and larger hybrid turbo. How much power do you want to make?
