1994 Toyota Camry V6 Supercharged Running Rich

Description

- Installed Supra Injectors - Rebuilt supercharger - FPR now NOT rising with boost pressure - Boost leak - hitting only 5psi - AFR flat 10's - SAFC settings currently around -20% Before turning down the fuel pressure and the FPR from rising with boost, the car was running so rich that once boost was hit, it was like hitting a brick wall (due to the URD unit). You could smell unburnt fuel beyond belief as well, and I would estimate that the AFRs were in the 9s if not 8s- unfortunately, the AEM wideband only goes to 10. Now that the mechanical side of fuel delivery is dealt with as much as possible, the REAL tuning starts with the safc... On a positive note- the very lean spot that I would get on initial hard throttle that I had before is now gone. It seems that the bigger injectors solved the problem. But also because of that, I'm afraid to turn my fuel pressure down too low to help lower my open-loop WOT fuel needs, or else it will also affect my low-end closed-loop fuel delivery. We'll see what happens...
