Hey guys, if anyone is interested in assisting with N55 testing and trying a new COBB AP
N55 tune for your 2011 335XI let us know. For those of you in in Mississauga/Ontario you'd get in touch with Dzenno and for those in Maryland you'd have to get in touch with me as tuning/testing would be local only (no eTuning). You can PM us here or email us at
sales@protuningfreaks.com in case you'd be willing to participate.
Again, it needs to be a
2011 335XI (N55)
