FAST-FLASH Power Programmers give your vehicle a 15 minute tune-up that unlocks hidden performance potential, yielding maximum horsepower and torque. The process is simple - just plug the programmer into your vehicle's under-dash ODBII port, and answer a few questions. Select from three distinct modes (performance, towing or economy), and FAST-FLASH automatically reprograms your vehicle's computer for idle quality and optimized air/fuel ratios. It also re-calibrates the ignition timing, transmission shift points and the speedometer for gear and tire changes
