If it's going to be a major repair, you bet they will read the ECU.
There's no doubt a custom tune will get you the most gains. But if you decide to eventually sell the car? What then? You basically lose all of the $ you invested in the custom tune.
With units like the Cobb AP/Hypertech, you can at least sell those later on down the road if you wish. No, you won't get the gains of a custom tune, but that is something to consider. I'd say these stand-alone units offer a good middle ground for someone that wants to squeeze out a little more performance, but doesn't want to go through the process of getting a custom tune.
They each have their pluses and minuses.
