    Custom OS uploaded, instructions are spot on, and the radio still works afterwards :wink:

    It doesn't get any better than that.

    Nice work Ross!

    If you still require your radio to work, you need a better sounding exhaust system.

    Ross,

    Do the custom operating systems have the EPA readiness tests like the stock operating systems do?

    Yes, basically what we are doing is taking the portion of code we need to modify, in this case the Octane Scaler routine and modifying it to our needs, the rest of the PCM code stays as GM had it.

    A 2bar tutorial, yeah that is needed isn't it. :oops:

    Cheers,
    Ross

    Question on the upgrading my OS.


    I have a 99 5.3L truck. With commercial version I can upgrade it to a 2004 O.S. and just use a bin from that year? or exactly how does it work?

    You 99 and 00 will love the 01+ OS especially if you are running SD
