CEL code #26

Getting closer on my tune and check engine light is on. Getting #26 - Mass Air Flow Sensor was greater than 0.7 volts with engine off (O), MAF sensor was not between 0.2 and 1.5 volts with engine running (R). Do I change the "MAF voltage minimum" to a lesser value than what is in my maf curve table? Or do I have something else going on. I would also like to add some fuel durring decel, should I decrease the low slope? It gets lean enough to make some coughing. I'm using Tweecer with an a9l.
