    Alright I know there are some guys on here that have used it so I'm hoping they can help me out. I have the software to install it on my computer but I'm not 100% sure which to install. There is the the black box tuning and Tune and Scan 7.5(IIRC) I assume I need the 7.5 installed and not the black box tuning correct? Also I have an updated tune that I got from the guy I bought it from. How do I go about installing this on the truck? It has 5 tunes on it for my DSP5 switch.

    Ok, as for the software, the lasted version of the tuning software is availble on EFI's web site.

    It sounds like you are newly installing the software on your computer so you need to install the EFILive V7.5 Scan And Tune Software For FlashScan V1, V2, AutoCal And AutoTap

    You will not need the Black Box logging yet. figure out how to tune before you start logging as you will not be able to make sence of the log without understaning the tuning end of it.


    If you all ready have the DSP5 switch installed into your trucks ECM, then from there you need to

    set up your V2 and your computer in your truck
    open the tuning software
    click the button in the top toolbar for read calibration from PCM
    save your stock tune (and don't loose it)
    then you need to preform a full reflash of the PCM with new operating system and calibration

    Hope that helps
    if you have any questions you can get me on the phone and I can walk you through it.
