Default 2 Bar OS and Emissions

Hello,

I am going to be putting a super charger on my father's car. But this car needs to pass Massachusetts inspection. Do the custom OS's that HPTuners have affect the emissions part of the PCM/BCM in an 02 fbody.

This also applies to 1 bar OS or a speed density tune.

All my 2 bar cars pass the testing up here. We us EFI live but I'm sure HPT could pass if done right.

Ah okay. I just wanted to make sure. I am keeping all the factory emisions stuff. I am just worried when you take the maf or change the factory operating systems, I just don't know how that affects things.
