I just installed a JB+ on my son's 335xi (2010) along with a Burger (Phoenix) charge pipe. We put the JB+ on 100% (purchased it second hand).
Love it. No codes. Noticeable power increase. Have no reference to any other mods. Couldn't be happier. On the other hand, I am still reading all of the threads covering the higher level mods.....
