They also provide simple mechanisms for you to turn on/off and alter the potency of the tune.
Obviously any tuning will introduce potential for reliability issues since you're pushing the components of the vehicle beyond their anticipated mechanical thresholds. That said, I think many people have found the JB tunes very reliable since you don't need to dial-in the maximum power all the time. These devices are also easily removable for visits to a dealer.
Honestly, I'm not big into mods. I think these cars, especially with the M Sport package, come very nicely equipped right from BMW. Mods are financial sink-holes. If the car is leased, the best you can hope for is to remove them at the end of the term and sell them at a serious discount to someone else. Maybe that's worth it to you. Considering the time and expense of swapping suspension parts, for instance, I wouldn't go there either on a lease. At most, I'd personally consider the JB for some extra power and maybe a set of wheels (easy to swap and sell later... plus, you'll likely want to get rid of the OEM runflat tires).
My two cents!

Excellent reply. Thank you for taking the time.
I'm completely on the same page as you with regard to mods. I dont feel like the car "needs" anything. I have a summer set of wheels (OEM staggered 19" from a 2012 F10), but I likely wont touch another thing on the car.
Just looking for a very light intake/ecm tune to sneak a few more ponies.
