It's not as easy as just swapping the ECU. The crank has a different reluctor wheel on it that has a different orientation and tooth count. To use the turbo ECU you'd need to swap the motor, transmission, axles, front wheel hubs, and entire wiring harness. That's assuming you redrill your brake rotors and wheels for 5x110, otherwise you're looking at new brake rotors, calipers, and wheels.
Getting a Trifecta tune is your best bet for performance out of that particular ECU. Otherwise I'd suggest picking up an 05-07 SS supercharged, they go for cheap and are a good performance buy.
