    1 bar sd to 2 bar sd switch

    I currently have a 1bar SD operating system loaded on my pcm. I am switching to forced induction and have a 2 bar SD tune for the kit I have. I have searched and found that I need to go back to stock operating system and then load 2 bar. Is this true? Would i be better just getting another pcm to use the 2 bar tune I have? Also if I load it on my current pcm would I be able to switch between the operating systems at a later date since both are payed for?

    Thanks for any help.

    Correct, just open the stock operating system, apply the 2 bar custom operating system, adjust accordingly & write entire.
    It doesn't have to be perfect, it just needs to be done in two weeks...
