Hi Guys,
I had a 2015 Challenger on the dyno with a very peculiar issue. Let's start with the car. 2015 6MT 5.7 with a P1-SC, boost cam, ID1000s, stock exhaust with cats. The issue is that it misfires at 2,500 rpm at any heavy load. I don't have an exact number of airflow but it absolutely does it at WOT every single time. Floor it at 2,000 and right at 2,500 it stumbles, and then continues on its way. Car runs flawless otherwise. Plugs were changed with no affect. AFR, ignition timing, and cam timing have no affect on the issue. Attached the map and a log file that shows the misfire at time stamp 1:45. Any insight is appreciated!
