    Why do you think 11.0 is lean?? Were you tuned at something different before? Or are you running a factory tune?

    07 Wrx . Catless turbo back exhaust, K&N short ram intake, MBC, access port Stage 2, Walbro 255 pump. I want to know if 11.0 is too lean or if its safe to run that much of an air fuel ratio.

    14.6:1 is what is considered perfect Air/Fuel Ratio, however most turbo cars are factory tuned around 12:1 due to the need of more fuel per air needed. You should be fine at the 11.0:1

    However, that k&n filter is no bueno sir. The oil on it will kill your maf sensor. Save yourself the trouble & get a new, non oily filter. Seriously.
