As I mentioned in another thread, before removing the two shims in my IA fuel head, my system pressure was easily over 100 PSI. I mean when I flipped the valve on my CIS pressure gauge test kit, the needle just pegged itself!!! I'm now dialed in at just 90 PSI with no shims. My AFRs no longer dip down into the 10s! The lowest I have seen on a third gear pull is 11.4, which quickly jumps up to 11.7.

Brian Leask indicated to me that you can file the shims down to fine tune your pressure...in other words, play with it...
