probably allows your laptop to talk to the ECU. Then you get to s/w to do so (make sure your interface and OS will work with the s/w). Then you get a data file with their best guess of that parameters that will work best with your engine and its mods.

OK..so I know this guy who has one of the most moded engines on earth. And it took him about 50 dyno runs and on the road runs to come up with the best set of parameters and mods he could devise. So do I think their best first guess is gonna be great for you...heck no. Unless they have had a setup just like yours on their dyno.

Just as your moding without a test dyno run after each mod to see its effect may be leading you in the wrong direction. Data should drive your direction.
