    AFR

    My AFR gives me 12.5 , when I decreas or increas the Fuel regulator it gives me the same number?!
    My RPM 8.640, so what's the ideal number for the AFR?

    You should be increasing the fuel pressure. 11.9 is ideal.
    What are your mods?

    Does your AFR stay at 12.5 throughout the entire RPM range ? Because I once had a bad calibration and it stayed at the the same AFR for the whole rpm range and no matter what I did with fuel pressure.

    From 12.5 to 11.9 AFR I need to decrease or increase the fuel pressure.? And I'm using 18psi ET R9 ECU 725 injctors

    when you ordered the R9 reflash, did u specify what AFR you wanted it to be tuned too?
