    Rpm drop on rev

    Stage 2 truck cam in 2012 Seirra. What table helps the rpm from dropping to 400-500 this back up to idle speed? I've tried increasing the Running airflow down low. Thanks

    Typically because its rich when the engine is decel. That cam will require VVE tuning. Not doing the tuning will make that situation worse. In the meantime you can add to the running airflow tables.
