Looks like a generic "piggyback" device and there's no reason it cannot do just what the labeling indicates. With light mods, like intake/exhaust, this ought to give more than enough adjustment range. That said, the further you deviate from stock, the more variables...and that's where life can become complicated.
The OEM will start with a base fuel map table, having hundreds of cell values that correspond to manifold absolute pressure (MAP a.k.a. vacuum) & rpm, with a throttle position sensor (TPS) enrichment table overlaid. Lastly, O2 trim allows the system to make on-the-fly AF adjustments and the ECU to "learn"; that only applies to the closed-loop portion of system operation. With a narrow-band O2 sensor, speed-density systems usually go into open-loop mode beyond ~50% of peak engine output. There's no "learning" function in open-loop mode, the base map values had better be right or you'll have a sub-optimal result.
Big increases in displacement, rpm and hp can be expected to greatly change airflow curves from anything the OEM could have expected when creating the stock maps. Thus, it's likely that doubling hp and increasing rpm 3K over stock will introduce fueling requirements beyond what the stock maps and a 3-band TPS-based module can cover properly. Issues could be anything from "hiccups" in throttle response to huge increases in fuel consumption, to fatal lean conditions.
Just like college "isn't the 13th grade", EFI setup & tuning is not carburetion taken one step further...it's another, highly-technical, world.
