I'm finding this out right now. With the colder (read: more dense) air, I'm getting a CEL and limp mode whenever I stomp on the gas. It's just a matter of adjusting the air flow limit table.

Now, as far as absolute maximums...I'm not sure.

Depends if the housing is stock. Many of the intakes come with slightly larger MAF housings which scale the MAF and increase it's capacity. I'm sure if you do reach the limit, it is a imple matter of getting a larger housing and retuning.

Thanks for that bit about the 'air flow limit table', I will do some research on that.

Thanks, the intake is stock, along with the AFS housing. Any numbers where that is concerned?

I'm looking for a power limit b4 the AFS/Housing or intake has to be upgraded or tuned to read more air.

It's mapped to about 415 g/sec at 5.00v

An average TBE Evo 10 with good boost control hits about 300-305 g/sec max which is about 4.54-4.57v

How did you arrive at that number??

I get 500g/s and you can rescale it if required

I don't know if that's enough for a GT35 though
