Cobb claims 14HP extra.
All these claims are sus, and you can't really just read dyno figures. I would have gone with Cobb if it was out when I bought the ESS as I like the data logging features.

Looking at custom tune options however though once everything is in. I have a friend who's just done a custom tune on his 335i by a guy who normally work on Porsche Race Cars so will investigate further once I sorted out my bolt ons.
