OK I'm thinking of buying a maf translator my friend has the maf pro but thats cost $400 buy itself. But he told me about the maf gen2 works the same as the maf pro but a little differnet. My question is the maf pro you can work with out your stock maf sensor does the maf gen2 do the same I'm trying to run with out the stock maf on my car causing trouble. Or does anybody know the differnts with this maf translator or there any other out there that does work with out the stock maf. thanks
