I have a 2012 G37xs coupe. Thinking about ordering Hypertech. I saw they have maps for the takeda and stillen intakes. For my setup I have afe drop-ins and hps tubes. Since the stock airbox on our cars is engineered pretty good, with my upgrades would it be smart to use one of the intake maps?

 

I would use the stock settings. Setting the tuner with an intake you dont have probably will make you lose power. Especially since takeda and stillen intakes are designed very differently from the stock intake.
