    Question How do these AFR's look?

    How do these numbers look?
    • Idle = 10.8-11.0 when warm
    • 4000rpm = 13.0-13.5
    • 5000rpm = 12.0
    • WOT = 12.5-12.7
    Mods in signature. FPR is currently set to static at 54psi. I'm thinking I should try 56psi, but looking for input. My concern is if this will have any impact on my idle and mid range AFR as it already appears as though I may be a little rich there?

    Too rich at idle. Get tuner to lean out a little at a time.

    I assume you are using a Maptuner? If so, just email Jesus Garcia in support and provide him with your AFR numbers and he will make a tuning adjustment for you.

    What RPM are you running?
    Idle is to rich for me. WOT could be ok, depends on the RPM's

    Agreed, and planned to correct that with increasing the FPR setting, but will that cause the idle and mid range to become too rich?

    What is the recommended AFR for idle?

    Using Dean's level 5 flash. Jerry, I thought the idle was rich and others seem to agree. What are your thoughts on the mid range AFR? Am I too rich there as well?
