I spoke with my contact for Superchips and he said the Flashpaq F5 Performance Tuner, part # SU2845, will help with your take-off and mid-range power on your 2011 GMC Sierra, however, the increase in power will vary from vehicle to vehicle.

Any aftermarket modifications to the vehicle will also affect the performance increases. The towing power levels will increase your mid-range power and the performance power levels will increase your take-off power. This tuner comes with other beneficial applications such as the Mileage XS saver which will help improve your fuel economy and a speedometer calibrator to adjust for custom wheel sizes.
