    Safest way to flash my tune on friends car.

    I have a 2004 Mustang gt auto that I have a few unlocked tunes for my car. A friend/coworker has a 2003 GT 5 speed same performance mods
    Is it safe to just flash my tune on his car or do I need to copy areas of the tune to his file.
    If so is there a easy way?

    How would you guys suggest me doing this?

    Copy/paste.

    Putting your tune on his car would open up a can of worms in some cases. It could end up costing you more credits too because you have to license his computer, then you'd be writing a different tune file into it, then it may ask you to re-license it because you created a new VIN/OS pair. Or something could go wrong with being different year computers and brick it.

    Safe bet is only license it once, then use the compare features comparison log to copy/paste changes you want.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
