Unless I upgrade the to a GM MAF. You need to adjust with a dsmlink to not run to rich.

Seems like this is a way to go. From what I read, you can vent with the upgrade MAF.

TRUE?

Also if I upgrade GM MAF with the dsmlink will that replace or work in conjuction with the OBD2?

Or is it smarter to avoid that whole setup and bypass the airflow instead of venting it with a SSQV BOV?
