05+ stock slot style maf sensor horsepower limit

[bg90coupe]

I'm looking to switch to a slot style maf in the near future. My car will make between 550 and 600 rwhp. Will a stock 05+ slot maf in a 110mm housing support that much power? According to vmp it will be right on the edge which I don't want to be. However lethal performance says a gt500 maf (same as stock 05+ maf) will support 800rwhp in a 4" tube. That's a big difference. My other option is the vmp3500 in a 4.25 Id tube which I know will work but it is the more expensive option.
