My max at almost stock (only BHR coils) was 208.58 @ 8727rpm on a hot day in June running the "stock style" map with the AccessPORT. I'll post up the log in a bit.

oh man, you don't want me explaining it, i am still trying to wrap my head around all this. Read the help file on Kanes site and the thread in the engine tuning sub forum. That will give you a better understanding

Since you have the ability to alter the calibration of your MAF, you change the amount of airflow the MAF registers under certain conditions. It's possible that you could change the calibration of your MAF at top end which would produce a larger or smaller number than actual.
So trying to compare two different RX8's airflow numbers and try to make sense of the power output isn't feasible because there's no constant between the cars.
Basically, don't get hung up on the numbers too much as each car is different.

Dang, well I logged some data and it seems im reaching a max of 243 g/s for my MAF, may be just a spike... Idk how yall are getting around 200, must be my AEM CAI??? Idk but at WOT from 8-9K rpms I see a steady 200+ g/s reading on my MAF from my datalogs, I seem to be getting a average of 215-225 around those rpms as well...... Ill attach them shortly...
EDIT: Apprently my file is invalid, any ideas at how to make this work?

Lol if I can find a way to post it I will... But I do get an average of 215-228 from 8-9K rpms no lie...

I think my guideline at page 1 is valid.

Okay guys, uploaded the Data to google docs.
FYI, I have a 6 speed manual, slightly modfied Cobb Stage 1 map (no maf scaling changes just fans, revs, etc), BHR ignition, BHR fuel pump, BHR midpipe, HKS catback, stock intake with WIX filter and custom cold air duct.
