I currently have a 2015 A3 with a Vortex xl turbo running E30. After getting a custom tune from EQT the car ran well for a couple weeks but after that the car started misfiring. The first issue was one of the hoses inside the gas tank that connected to the LPFP fell off. Also one of the hoses inside the gas tank connecting too the LPFP was little bent but I managed to straighten it out. While doing the custom tune some oil got passed the PCV causing white smoke to come out. The car has 3.5inch CTS downpipe, CTS cold air intake, CTS inlet pipe, 1300cc CTS mpi kit, EQT charge pipe/ Turbo Muffler Delete, APR intercooler, Upgraded 5 bar TMAP/PUT sensors, Stage 3 DSG tune, NGK racing R7438-9, APR Coil Packs. I have tried replacing my APR coil packs with the OEM ones, no difference still Misfiring under WOT. Spark Plugs have just been changed no difference. AFR was at 9.55 when doing one of the pulls. I will leave the picture of my cobb with 9.55 AFR same with a VCDS scan and 2 logs I did that day with the car misfiring. Also the vcds scan was done at the start of my problems but currently the misfire doesn't trigger any codes. Thank you for the help.
