Misfire Cylinder 1

ok without writing 5 paragraphs ive had plenty of idle and running issues with my 08 335i... The dealer I go to sucks so I want to make that last resort. I threw code 29CD - misfire cylinder 1! Dealer replaced Hpfp and injectors 1, 2, and 3 (hassle). car is out of warranty! I replaced plugs with Iridium NGK's... what could be the problem now? Coil pack? also i have JB4 DCI and DP's.

Move ignition coil to another cylinder and see if the problem follows the coil.
