JCW ecu tune and exhaust... Can I just get the tune?

Would mini just sell the ecu performance tune-up so my f57s can get the hp increase without the exhaust update?

I really like the sound of the s exhaust. Not to loud but puts on the noise when pressed.

I know an Independent Mini/BMW tech in Raleigh, NC that has the tune. He sold the exhaust only to a member with a JCW and as far as I know still has the tune available.

just buy a aftermarket tuning box if you only want a boost in hp , the jcw exhaust adds no power just sound.

I don't think this is true. With the flap open, it seems to add about as much as the AWE exhaust looking at the dynos available in this forum.

JCW Pro exhaust adds 8 bhp with flap open compared to closed from dyno results I've seen.

Catless downpipe adds around 15 bhp from results I've read about
