swapped out 5 / 6 spark plugs (since one cyl had bad threads and needs to get re tapped probably) with PERFORMANCE IRIDIUM SPARK PLUGS - NGK ..changed map to MHD stage 2 + and misfire went away... i uploaded two logs with 3rd gear pull - 2.5k to 7k

Car is a 2009 BMW 335xi N54 with a 6 speed manual with 76,000 miles Currently at FBO status: VRSF 7" intercooler ( not HD, but regular) VRSF N54 Catless Downpipes Relocated VRSF Silicone High Flow Inlet Intake Kit VRSF Chargepipe TIAL (red) BOV M Sport Exhaust burger tuning catch can I ordered the Performance Iridium Spark Plugs - Set it should arrive Friday 25th and i plan to install those this weekend in hopes it will help. I had Brenden recommend me to get them. Currently driving the car on Stg 2 only because the stage 2plus (fmic) allows for more boost and causes misfire - at first it was misfiring cyl 1 and 6 so i swapped out the coils with some extras i have and it went away..then a week later same thing but cyl 3 and 5 i belive it was. Have not changed those out - but tried just stage 2 and it seemed to not cause any issues.
