2012 Auto Dodge Charger with a 448 and 243/253 .623/.623 112 + 0 Cam Help!

Hi, I need a little help with a car. I really only played with a few Hemi's and nothing this radical cam wise. I understand the GM world but this is totally new to me. Any help would be appreciated. The car is a 2012 Automatic Charger with a 448 at 11:1 with a healthy 243 / 253 .623/.623 112 + 0 cam longtube headers. I believe it has 60lb per hour injectors but am not to sure. I'm using a 2016 Hellcat injector data to start and have modifed the VE tables to get the fuel trims close. The car also has a 3000 rpm torque converter. The owner got the car running on the stock tune and I have a cylinder 5 misfire. Pulled the plugs and the are black. Gonna have to replace the plugs before i go further. Just trying to get the car running stable at idle and seems like when I give it some gas is just comes down stumbles and stalls. It has a Hellcat 92 mm throttle body which I really don't have an idea what tables to get it to idle better or stable. I did put it in gear and it sometimes just stalls out. Are their settings to adjust for the higher stall converter.I'll post a tune file and log file if any one wants to help out. VVT and MDS have been eliminated. Thanks in advance.
