Fast Fuel Injection Help

[tjc]

I just bought a stage II car with FAST fuel injection. I was just wondering if someone could help me figure out what my air fuel ratio should be targeting for. The O2 is in the stock location. What would be a safe number and what would be on the edge? Any help would be great.
Thanks!!

If your O2 is in the stock location then you want to move it. Stock location is before the Turbo, FAST says it should go downstream from the turbo. Before the turbo from what I'm told will make it go bad faster and they are expensive to replace.
