Just recieved my SCT livewire with only Cann Tunes. I've loaded, tested, returned to stock, changed settings, reloaded, multiple times. So my question is now, with doing all that, does that overtune the truck? With that, could it make the truck feel sloppy/different/not as strong as it was on day one.

Some guys have asked this before or more along the lines of the tune loosing the oomf it originally had after several loads.

I haven't loaded and re-loaded too many times yet but I will disconnect the batteries so the truck can do a re-learn. I don't know if that really has any effect or if the way you stated your question causes any complications. I think it's perfectly fine to re-load and mess around without any problems and I haven't read anything factual about any side effects.

Ironmover is right. Your truck has to relearn some things when you change the tune. It takes about 35 miles or so of driving in varied conditions for the tranny to relearn. Also when you first upgrade from stock the difference is new and more noticeable. After a bit of time with a new tune you get used to it. I have only put my truck back to stock once in 2.5 years and that was to get some warranty work done. I reset it in the dealers parking lot and loaded my tune back in before I left with it.
