    Lightbulb VXR Cams - 2014 FX SVHO

    Hi All,

    I was looking over the RIVA tuning library and did not find anything around VXR CAMS or even CAMS in general. Someone on a different thread said to email JesusG (Already done - waiting for his response). My question is, does anyone have this tune complete with their MAPXTuner?

    Support told me the following, but not I am not dedicated to the Stage 2 SVHO 8600 AGR. Just not sure what is my best bet here.
    We have not run that tune with those cams.
    It should be ok but we strongly recommend that you use datalogging to get
    the AFR for this setup.
    (This would require an O2 sensor and datalogging app.)
    If you send us that data we will be able to check the tune for safe
    operation and to adjust the fueling to get the best performance.

    Jesus has something with the cams for sure. Data logging will always clean up the tune for your setup

    What does swapping to VRX cams do for the SVHO?

    More air and fuel. Bigger lobes.
