Does fuel pressure gauge tell A/F ratio

Well, the stochiometric air/fuel ratio is 14.7:1. The Autometer A/F gauge measures this based on input from the 02 sensors. To be truley accurate, you would need an EGT (exhaust gas temp.) setup that measures each header primary. We just installed such a system on my dad's comp dragster, but it is way out of budget for a simple street machine.
Unless you are planning on running a lot of spray or boost, I really don't see the need for any air/fuel meter on a street car. Can you hear detonation? On 93 octane with a good chip program detonation shouldn't be an issue.
