    No RTT for 3 Bar OS on a 04 Vette

    I upgraded from a 2 Bar OS with RTT to a 3 Bar and there was no RTT option. Did I miss something or is it not available?

    I had the same thing happen to me with my truck. Apparently the OS you're probably using doesn't support it. A different OS probably will, but as I was told, you'll need to burn another 6 credits to get it (2 for 3bar, 2 for RTT and 2 new OS). You could try and ask if HPT will help you out. I'd like to know as well since I greatly miss RTT.

    Post your stock .hpt file
    It doesn't have to be perfect, it just needs to be done in two weeks...

    Bill,

    Here is my old tune prior to the 2 bar and 3 bar OS. Anything you can do to help is appreciated.

    The 1 bar SD, 2 bar SD & 1 bar maf w/rtt all come with RTT. The 3 bar custom os doesn't and we won't be adding it. So if you want RTT you would need to use the 2 bar custom os in this case otherwise you'll need to just have to deal without it if you absolutely need the 3 bar support.
