JB1 N55

Hi all - I recently purchased a 2011 135i M sport equipped with a DCT gearbox. I would like it to go faster, so I am about to purchase a N55 JB1. I would like to know if perhaps if there is a better option that I should be considering.

Oh no. I'll get the popcorn...

In my opinion, the two main tunes will give you similar results. Do a bit of searching on this forum and you'll see the pros and cons of each one.
