I have a 76mm C & L mass air unit calibrated for 24lb injectors with oem black box. What does the mass air box to? I am having problems with a lean condition and the computer errors tell me the voltage is low at the O2 sensors causing a lean condition. How can I test the black box on the mass air flow meter? The O2 sensors are new and I'm trying to figure out what the problem is, any input is greatly appreciated!
Regards!

what mods do you have?

Did you disconnect the battery when you put the new 02 sensors in? When the 02 sensors read lean there can be a bunch of problems, like low fuel pressure, a air leak, and exhaust leak. The MAF sensor must be tested with a multimeter for power ground, and signal going to the computer.
