There is definately a market for these things but not with expensive performance cars that were designed from the factory with perfomance in mind. The only real reason you would need to alter the management is if you whacked in a turbo or supercharger and in this case you would probably go for a full ECU solution like a Motec that can be tuned on a dyno for your car.
A lot of my freinds have experimented with UNichip (mostly jap cars) and I am yet to be convinced of any benefits. Some of them also resulted in a poor idle, running etc after the chip.

Well the reason most people use a product like this is because your NOT going to get any use out of all those after martket bolt-ons like a cool air intake, headers, exaust, etc... without remaping the stock ECU. So if you like your stock Boxster and have NO added bolt-on performance upgrades, then sure by all means leave the factory ECU unchanged.
