VAFC settings for Walbro 255lph

I just install a Walbro 255lph fuel pump in my car. All I have is an AEM intake and an exhaust with 2.2 inch piping from the cat. My fuel pump went bad so I decided to get a high flow instead of stock cuz I'm going turbo soon. NOw that I have the high flow pump, I believe I have to change my VAFC settings so that I don't flood the engine with too much gas....especially when VTEC kicks in. Any experiences with a situation like mines? What settings could I use to regulate my fuel now?
