Actually if you're within about 10-15% of of the stock calibration and the O2 sensor is still switching around lambda 1, pretty much any EFI system will adjust its long term fuel trim accordingly. Once you get to the limit of your engine management systems flexibility, it'll trigger the CEL. There is no real in between. Barring any fuel line issues, any EFI system should be able to hand anything up to ~ E30.
