    what are the modifications done to your vehicle? what kind of vehicle?
    what you trying to achieve?
    if you're not familiar with tuning or scanning and what the terms mean, and what to look for it's going to be difficult to pass on any recommendations.

    you might wanna look into a custom tune if your vehicle needs major tuning.

    go to data streaming and monitor from the list long term fuel trims on both banks 1 and 2, Monitor spark retard, and timing. Go to your LTFT and see where they are at 2k rpm with cruise on. Should be around 4-5%. Go into customizing the tune and under injector slope take how ever many % out till the LTFT reads 0 to -2 % and thats where they should be. As far as spark, make some WOT runs. If you see no spark knock then adjust the timing up some till you see 1% and back down 1 degree of spark. 0KR is advised. The power enrichment will have to be done at WOT with a wideband AFR guage. 13.0 to 12.8 is desireable normally aspirated. Hope this helps.
