Frank,

Do you happen to know anyone that carries the fel-pro system, or
where to get more information on it.  With the std 02 sensors my 
plan was going to be to first get the fuel curve level (same O2
voltage) and adjust the level until I appear to get the best HP,
life would be much simpler with a system that would get the fuel
curve level by itself, then just figure out exactly where the
best a/f ratio is (I know somewhere around 12.5 for power, 14.5 for
mileage).  Thanks for any help
