stay with the ls1 maf....screened.....I still have mine. Lots of people have made great power with the stock maf. You are gonna peg the mafs readings against what the stock pcm can recognize anyway. The pcm is your limitation but you can tune around that. You
can keep what you got up till around 650+rwhp and get the tune pretty damn close
