Hello, I am having some trouble creating a popcorn tune and was looking for some advice. I currently have a 2014 charger v6 with no cats or mufflers. I have messed around with the dfco values and the spark table and am encountering a problem. Whenever I change the values to be lower the car instead of popping seems to ?idle? at around 2k rpms. It sits there and jerks for a bit and then idles down. I think it may be ?rev hang? but I am not sure. If anyone could help me create a popcorn tune or help with the issue that would great!
