    Default can't stop hitting reduced engine power

    I tried to max out c6101 and it didn't stop the reduced power problem. When i retreve the tdc codes but there aren't any that explain why the reduced power mode is being triggered. All the transmission process enablers are turned off from the factory in the ecm and in the allison program there aren't any process enablers to turn off. I get the feeling the problem lies in the tcm telling the ecm to reduce power. I turned 1514 code off and 1781 off but still the reduced power comes up on the display next to the tach on the dash. There aren't any custom operating systems for the allison control modual yet are their? 604 cu twin turbo gas with allison 5 speed originaly 8.1l with allison 2001 4x4.
    any help would be great
    thanks

    rgullett83, the engine in this thread is a 8.1L gas motor with an Allison TCM and an LS1 PCM, whatever problem you are having it is not related to what 496chevy is tuning.
    I no longer monitor the forum, please either post your question or create a support ticket.
