    VVT and MAF tuning?

    I have a couple questions,

    1 - Should I tune the VVE first then the MAF or MAF first then the VVE?
    2 - Can I tune the VVE and just run the car in VVE mode open loop?

    1. doesn't matter, I usually rough in the vve, then tune the maf, then dial in the vve exactly.

    2. yes you can but there is no reason to do that unless you have some specific problem running a maf or oxygen sensors.

    OK I did have a problem with a 2015 boosted Silverado, big cam wouldn't want to run or fix the fuel after turning on the o2's back so I just run it MAF open loop.

    Been my project truck and been reading a lot and see that this new vehicles run through the VVE better.
