I hear the stock maf is good till about 550 rwhp, which is where im hoping to be.

can i keep the stock maf or do i need to upgrade and with what?

i had a granatelli but just put the stock one back in.

if you are going to be running a 90mm lsx then you need a 85mm if you dont get a 85mm maf you arent gonna hit 550

Not true at all

a stock metal body MAF will read enough air for ~650HP at the flywheel. An unmolested 85mm will read less due to the flow curve it has.

You can do it on either, but tuning will be a little different depending on which one you choose.

so your saying he should run a 78mm maf with the 90mm lsx setup? im not saying the 78mm maf cant read that much hp im saying its gonna be a major restriction in the 90mm lsx setup.

He can. While it might be a restriction, it can be done w/ the smaller MAF. It'll be less of a restriction w/ the 85mm on there, but the tuning will be different like I said.

Question was can he use the stock MAF, sure. No mention was made of which manifold/TB is going on the car.
