    Custom OS question

    So i have a 99 GMC , 5.3, P01 ECU
    I have been tinkering around a bit getting my feet wet with this platform learning the ins and outs before i decide to bolt up a Kung Pow Cam Crusher and send parts into orbit.. ... anyways, When i click on the OS icon i have ZERO other options. i thought maybe it was because i have done some editing so far so went back and looked at my stock tune file still nothing. Thinking maybe something is goofy with my ECU i read the stock files from 2 of my buddies pickups and neither one of them show and other OS options either, just blank screens when i click on the OS icon. Any advice much appreciated.

    Are you in advanced view under the edit tab?
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
