Tune for descreen MAF

[Colossus]

I have a friend running tuner cats. He's going to tune my car for because its running pig rich but he needs a file for descreened MAF. Any ideas where I could find one?

Well if you have datamaster I would datalog the car and do some math with the blm's to see what it needs I ended up rescaling the mass air flow tables and got the whole scale real close.
