Yeah Matt from Nistune did confirm the following on a reply email:

"You should only have 12V, signal and signal ground (ECU signal ground) connected to the MAF from the ECU. Do not connect to chassis ground, otherwise it may mess up MAF readings."

Other fun fact from his email:

"ECU uses a calculation where TP = MAF/RPM x K constant"

TP stands for theoretical pulse width which is what the ECU uses for engine load. This is derived from the above equation.
