Any ideas guys? Ran the RAFIG and RAFPN today which helped the idle out. Truck still drops very low in the RPM range when coming to a stop and wants to also almost die when the fans/a/c comes on. I played with the fan airflow table which helped, but i wasn't sure how far to go. Here is my latest tune/log file. I also noticed that my TPS is always reading 14-19% at idle. Is that normal?
