As I understand it Chris has specific maps that he burns in depending on application. Obviously depending on the engine different firing order and injector sizes as well.

Chris has been building these for some time now so I'd imagine working with builders like Keith it's about as good as it'll get.

Biggest advantage to the system is also it's biggest problem, the mass air meter is not in a good spot right on top of the throttle body. The oxygen sensors are located at the collectors in mine, again not ideal, but side pipes aren't real O2 sensor friendly (or headers for that matter).

About the only real problem I've heard of is that the system doesn't adapt itself real well to altitude changes (although it does have a barometric sensor). This may not be an issue anymore as the system has evolved over time.
