You will see very little gain on jb4 but you can try it on a dynojet and see different maps on pump gas and then do the same with either e85 or racegas (should add some more power).
I think all the ECU tunes for M2 are still being tested thoroughly since it runs more boost from factory.

Also seeing Terry's comment on n54tech forum he says EWG wires add-on not needed for M2 unless running meth.
Told me it was not needed for my X4 M40i as well after testing different maps with EWG add-on plugged in.
