A custom chip is only good once you have other mods as the manufacturers do a pretty good job getting the most power out of the engine. Once you start changing the engine's performance characteristics, then you can change the controller.
Yep, I forgot to leave that point out. Only chip if you have done some performance mods to your car...even just a new intake and exhaust could benefit (a bit) from a new chip. Of course, if you have a car that comes with turbos...say an Audi S4...a chip would definately help even with no mods.
