    Hmmm, have you tried swapping an ECM in from your dad's truck?

    Also, maybe flash it back to stock and trace any mechanical issues, if there's something physically wrong tuning cant fix it and will do weird things!

    I thought about trying the ECM swap and seeing, may still do that. I'm thinking it is something mechanical or a faulty ECM. I know he bought the truck used and originally had a PPE programmer on it. Thanks Erik!

    Hmmm wonder if the PPE left some residual stuff in there. Seen it before with Hypertech/Superchips etc so it wouldnt surprise me. Try the ECM because it only costs you a few minutes of waiting for the security relearn, then go onto mechanical stuff.

    I will try the ECM. Even if I do a full reflash of the stock tune, any residual stuff will still stay in won't it? I hate that.... lol

    Maybe, if its in the actual OS then EFILive should overwrite it with a full flash...cant hurt to try full flashing the stock OS back over then the tune over it.
