ecl98pse: It doesn't look like they offer a 9:1 disk. How much fuel you need also depends on what turbo you have. The Star turbo will need a little more fuel than the HRC at the same boost. I've built some fuel system pages that you may not have seen. Read them here:

Just remember that the FMU disks may not change the fuel pressure as much as advertised. Tommy tested several disks. I think the 8:1 gave appropriate pressure for 9 psi (check with him). Also, you should know that the in-tank pump with the star kit can't "safely" supply enough fuel at 100+ psi fuel pressure needed for 9 psi on stock injectors.
