Powerful handheld tuning.
These Tuners from Granatelli Motor Sports allow fine-tuning of timing and fuel curves. Each unit offers a multitude of performance tunes. They adjust speed limiters, adjust speedometers for gear and/or tire diameter changes, and have an adjustable rev limiter for a broader power band. These tuners allow you to adjust the shift points in vehicles with automatic transmissions, and increase line pressure for quicker, firmer, more precise shifts. Other features include the ability to re-tune vehicles after factory re-flash of the PCM, and a flash tool that allows custom-tuned downloads. These tuners also feature an exclusive multi-vehicle diagnostic tool with live data monitoring and fault code scan/erase capabilities. They install in minutes and won't void your warranty. You can also go back to stock settings easily, so you have unlimited options in your programming!
