Default Procharger guys inside!
I just bought the Procharger race bypass valve and was wondering if you can vent to atmosphere with a maf setup, or do you have to have an sd tune?
I'm kinda new to this so help would be nice. this is on an lt1 btw

You can vent to atmosphere with a MAF. I have been doing it with great results. It is going to be loud though.

Does it matter if the maf is before or after the bypass? The reason I asked is because I tried to vent it to atmosphere before but my car wouldn't even run?

I run my MAF after the Bypass valve. I have the bypass valve about 2 feet from the supercharger outlet, then the intercooler, right on the intercoooler outlet I have the maf. So far so good.

Mine is vented to the atmosphere. MAF is after the bypass.

It has to vent before the maf or it's reading unused air.

The MAF needs to be between the bypass & the TB.
