From my research, I found that all intakes fitted on the FN2R will produce a very rich AFR, even the base map on flashpro (group N) is fairly rich but with its convenient live datalogger it should be fairly easy to tune the AFR. If you intend to mod your car definately get flashpro, ive heard great reviews about it. For now, im going to revert back to stock airbox before i have enough funds to change manifold and catback and pay for a full tune.
8.6L is very efficient! Mine sits anywhere from 9-11L/100km depending on how I drive.
Anyway, if you do go ahead with flashpro, please keep me updated on the progress and results!
