    2008 silverado regular cab 4.8L automatic. tune advice

    First i would like to say thank you for anyone that looks into the thread!!

    If anyone wouldn't mind looking at the stock tune and give me some ideas on things to change, I would greatly appreciate it.

    truck has zero mods other than a better flowing muffler.
    has cats and stock manifolds.
