Put A GReddy CAI on my 13 Si have flashpro didnt install any maps just did some data logging noticed doing 3rd gear wot runs
from 4800rpms-7100rpms it goes to 10.14 a/f didnt get a retune or load any maps.

My 2012 ran very rich after my AEM CAI was added. so much so, it bucked at 5,000 when VTec kicked in as there was too much fuel for a proper burn.

I've heard people say to pull the battery cable and let the ECU reset, but if you just pick a base map it'll make a heap of difference. Get a full dyno tune if you really want all the benefits of a cold air intake. Tell your tuner you want a hybrid AFM and MAP tune though. My car is AFM under normal to moderate driving and when I mat the pedal to WOT it switches to MAP tuning and VTec drops to 4,500 instead of 5,000.
