    2 step low octane trigger

    I have an msd 2 step box on my 5.3 with an s480, looking to retard the timing without effecting drive ability, how can I trigger the low octane table to be used when on 2 step only?
    Or is there other ways I should go about it?
    Any help greatly appreciated

    isnt that the point of the msd box?
    only thing ive come across is people shorting the iat sensor for nitrous.

    With the box I have you can only set the rpm limit that it misfires random cylinders,
    If I pull heaps of timing in the high octane table it makes boost quickly but I hit that area under light acceleration when crusing and it?s no good. Cheers
