We have a 2011 N55 335i xdrive and would like to add tuning software. I have never done this with a BMW before, but a quick internet search led me to some interesting options. The Burger Motorsports stage 1 and stage 2 seem to offer a nice plug and play option for a low price. Turner Motorsport offers a reflash of the current computer. Turner's prices seem to be pretty high for something as simple as a reflash.

What have some other people used? Do you have any good/bad experiences to share? I would like to keep my warranty and service plan in tact, while gaining some hp and tq levels.

Talk to the guys on the N55 tuning sub-forum. If you have the $ I'll suggest DINAN, as it keeps your warranty intact. For a cheap tune I'd use the JB4.

If you would like a JB4 I have a brand new one in a box for sale with the USB. Its for the N55. I can send picks, however I would have to open the box. I bought it from **********s for close to $600, but will sell it for about $500 including shipping. One of my buddies gave me theirs so I never opened it. Let me know if you are interested.
