    The truck runs good just seems like it needs some tuning.
    Since the tune is already credited would I have to use my credit(s) to switch OS.

    Did you take a look at the log and ltft histogram tables that I had? do they seem like There consistent enough that they are actually true? Is this speed density now or is a SD operating system required to run in SD

    It won't cost you any credits to switch to the HP Tuners 1 bar SD mode.
    You're already in SD mode. The HP Tuners Custom OS will eliminate the secondary fuel table and simplify it.
