Power Programmer
The ProFlash is a powerful tuning tool that allows you to set the level of tuning that you want. This is done using separate engine and transmission files for your Hummer, allowing you to change to the mode that you want to run. The octane level and ping control can adjust for fuel quality in different areas of the country and different altitudes. The ProFlash can also correct for altered tire size and for ring and pinion changes. The speed limiter can be set to stock, 130 MPH, and unlimited.
