If all cars are different how come the manufactures get away with the same tune?

Logically, you are 100% right. Theoretically, 100% right. In practice, not so much. All cars are a little bit different and unfortunately that means they respond differently to the same input. They obviously are the same car as you say so you can get away with a tame tune-up that will work on most of them, however if you really want to squeeze the most from a tune, you have to tune specifically for that car. Keep in mind that doesn't only mean squeeze out the most hp, it also has to do with driveability and reliability.
This is not Stillen's problem though, obviously it the issue was much more punctual. Its not that Stillen can't make a single tune that will work on everyone's car, it's that there's one glitch that is keeping some cars from working properly.
That being said, I don't know why anyone who has access to a tuner would not get custom tuned. Unless you need to be CARB compliant or you want to have the engine warranty, I would recommend getting a custom tune. If you can do a dyno tune, followed by a road tune...thats the best case scenario.
