Was just able to pick up a used FAST 90/90 and was wondering if a MAF upgrade to a 85mm would net me any gains and if so the best to go with. Or, with my setup should I stick with the stocker. Yea I know the stocker will "support" 500hp but it seems to me my stock MAF is a restiction with the bigger 90/90

I would upgrade to the 85mm MAF and Lid if money isn't an issue. IMO

I did it, figured the extra opening (90mm) could use more air plus I have H/C already.

Could you feel a SOTP difference?

I did it all at once so I don't know how much is the 85mm. But yes, huge difference over the LS6 and stock MAF/TB/MTI lid.

Go to your dealership and get a maf for a 2003 ZO6. Comes from the factory without a screen, will be pretty well calibrated. also you can get A maf repair harness for the ZO6 and do away with your iat sensor in you airlid. looks cleaner and works better.
