This is not to knock @biodiesel because he’s just repeating GDE, but this is the statement that makes me cringe most. It is so vaguely true that if you don’t understand you think you’re fine. Yes if you flash black to stock then all you will see is the stock tune. That is 100% true. GDE is just “neglecting” to mention all the other systems working in conjunction that are recording and tracking where you can tell changes have been made.GDE will even tell you that their tune, for the sake of warranty and other dealer visits, is undetectable once you've flashed back to the factory tune via GDE flash tool.
