I have a Stock MAF, and a GMS MAF. THE GMS isn't the NOS one. But, when I spray should I use the GMS MAF and just use my MAFT to richen up the mixture? Or is the stock MAF still better? (My stock maf is not ported or descreened)

I use the stock one with the screen removed works great . Ithink I read on some post that some of the after market ones lean out your car.

I've seen some GMS's add 4 deg timing and lean out the A/F.Not good with Nitrous.
I would start with the stock unit then when you can A-tap or Dyno with A/F try the GMS.
