    I have a Gen 1 speed3, it runs great. I noticed though that my AFR today was 14.26-14.41 on cruising. I thought it was closer to 14.7 before…

    mods:
    • 3” turbo xs catless downpipe and testpipe
    • 3” custom aluminum modified mazdaspeed brand intake
    • Autotech high pressure fuel internals.
    • Damond Motorsports Oil catch can.
    • Resonator delete stock exhaust
    • OTS+ freektune tune
    • Cobb Accessport v3
    • Had to replace the crankcase breather hose with just some rubber gates hosing as it didn’t fit with the intake.
    The car runs really well, just a bit rich. I’m hitting 15+ psi boost in 3rd, no performance losses detected.

    Is this 14.26-14.41 AFR normal being tuned? If not, where do I dig to correct it?
    I took a look already and my intake and connections on it seem solidly mounted.

    Thanks in advance guys.

    Justin at Freektune got back to me and said +/– 0.5 of 14.7 is normal. Crisis averted lol
