Oh ya. On my first start up the car would barely run. My wide band was pegged at 10:1. Most of my new fuel map is pulling duty cycle back with negative percentages. I am running positive percentages in high boost. The FIC actually zeros out (no intervention) at about 2 psi of boost. At idle its negative 27%
