Just picked up a stock 2013 135is with DCT. I've had a 2007 335i for 4 years so I am very familiar with the N54 world, but new to fairly new to N55. I've done some research on the various tuning options: BM3, MHD, JB4. It looks like the PWG that my car has causes some trouble when it comes to tunes. Which tuner provides the best maps for PWG engines? My research suggests that MHD is slightly better than BM3. I'll be using OTS maps heavily. I've tried custom tunes but never had much luck, the OTS maps seemed better and more refined.

On my N54 I've had JB4, Cobb, and MHD. I liked MHD the best in terms of OTS maps, smoothness, and driveability. And I have the D-CAN cable.

In terms of mods, I will quickly be adding an intercooler, DP, intake, and CP.
