The engine (by-way-of the DME and its input signals) will use whatever fuel amount within the "performance map's curve" that is allowed.
I'm not sure what you meant but it implied that it reverts back to the stock program. When you download the performance software from the Shark Injector, the stock program is replaced with the new program. There will be places (points) on the performance software's map curve that may duplicate the stock's curve but it will be from the performance software's curve not from the stock one.
I talked with a guy at dynospot and he said the same thing C.Yang said, so I can confirm that, but he was talking about the Shark Injector, not a chip, there's a difference. The Shark Injector just reprograms the car, but the car will go back and use the "more efficient" fuel map.
