    Question 2012 Cruze, first time

    First off brand new to tuning, never done this before and wont touch a thing till i have a basic understanding of it. I will be getting a wideband in the next week or 2.
    first thing i want to fix is my LTFT is seems to be way lean?
    have a ported manifold, and short ram intake 3in ID

    i have since added more logging parameters and will update
    I am not asking for a tune but rather where i should start?
    been watching goat rope garage, HPA, driving4answers, hp tuning live trainings etc..
    I figured after wideband install then, tune maf-speed density-.. where to....
    as a daily i dont want to blow the thing... yet, but do plan to learn and push this thing a bit farther HP wise.

    Here's the tune, and 3 logs for
    start up to running temp
    easy drive to work ~2mi
    hard drive home ~2mi
    Fuel: pump 91
    Mods:
    Ported intake manifold
    short throw intake

    If you changed intake tube then that screws up the maf settings. If the tube diameter changes where the maf is actually mounted, it really screws up the maf.

    What kind of fuel are you running? And what kind of hardware changes do you have on the engine?
