I have a vortec supercharged 2001 Mustang GT. Mafia on setting 3 with Cobra MAF. Tuning with Advantage 3. Tuning has went ok until WOT tuning. When I’m WOT, the load instantly spikes from the steady 1.24 to 2.0 causing EXTREMELY rich conditions. How does the ecu calculate load at WOT? It is almost like something is failing, but if you let off the throttle it goes right back to normal. Scaled injectors and displacement, But is there any other airflow that needs modified? Tried on setting 5 and was getting the same result. I’ve burned 50+ try’s at this and am at a loss and really want this car done.
Thank you for any and all help with this.
