35 PSI is a median value just for sanity checking and applies to the stock
Mazda injectors.  Fuel Pressure varies with manifold pressure  (if your
regulator is working right) and goes between about 32 - 40 PSI.   Don't
sweat the small stuff or read everything I write as if it is carved on stone
tablets :>)
