Takeda cai datalog and running rich
 

Hello,

Just curious, has anyone with the takeda/afe cold air intake actually datalogged their car? Reason I ask is because I seem to be running rich with this intake. My LTFT are negative 15% approximately in both banks. Could that potentially mean that this intake is not flowing better then stock? I thought a better flowing intake would lean out the car.
I thought it might be the shared filter so I replaced it with 2 k&n filters but still same readings. I also tried resetting the ecu and cleaning the maf sensors and now I am running out of ideas. I want to get my car tuned but I want to make sure that these intakes are in fact better flowing than my stock air box before I do.

Thanks and input will be much appreciated.
