    Question Fuel Trims at WOT

    I'm new to tuning Camaro's and I'm really unsure why during WOT at 3mins and 8secs the fuel trims to out of no where come back. The command AFR goes from 12.45 to 14.7 what am I missing for this to happen? Also I just started adjusting this tune trying to figure out what ProCharger did to this can tune.

    Car 2017 LT1 with P1SC ProCharger and Stock exhaust.

    Can't see anything useful in the log as there isn't much being monitored. Maybe it dropped out of PE (Power Enrichment) mode. Definitely looks like you are out of fuel by that injector pulse width though, right before it goes lean.

    I will added PE to the log to see if its kicking out. Have any suggestion on other parameters that should be logged?
