Default What IDC% are you guys seeing with a stock cam and stock injectors

I was just wondering what IDC you guys are seeing on bolton trucks... Mine is 84-86% on my last couple of logs just wondering if that is normal for 4.8 and the mods in my sig... My AFR at ~6000 is 12.5-12.6 and timing is at 25*...
