My M240i's both have the MPE and have since new, but they took a couple of thousand miles to get "fruity".
My X3 M40i has 100 miles on it so is still on the quieter side, but it sounds better than a stock M240 without MPE already so I'm hopeful.
Haven't actually used sport or sport+ yet but I might have a go this weekend 😁
Will report back.
