a few ppl have told me its not really lag its throttle responese that is majorly effected. The lag is usually like 100-300 rpm i wouldnt think was major. im just curious thats all coz im looking at putting a fmic aswell on monday.

There is a little lag but not enough to bother me.. since i put mine on i noticed a lot more pull in evey gear.. Stonger and doesnt puff out so quick.
Defiently worth doing if its what ur after

i call bluff.

what do you call full boost? 8psi?

19psi on my Fozz. If you have a good intake with a well designed FMIC and good tune, you shouldn't really notice the extra lag.

I suppose you can use some mathematical formula to prove there is a larger volume of air that needs to be catered for, but it is hardly noticeable in real world driving situations.
