Show original supplier description
The Advanced Fuel Dynamics ProFlex DX Adaptive Flex Fuel System is a patented, plug-and-play solution for 2018-23 Mustang GT, Bullitt, and Mach 1 models equipped with the dual injection 5.0L Coyote engine. This system enables you to run E85 fuel, resulting in enhanced power output and cooler engine temperatures. With over 2,000 miles of rigorous testing, it's engineered for optimal performance and durability. Key features include the patented BlendSense™ technology, which adjusts in real-time with a 30-millisecond refresh rate, allowing you to seamlessly switch between gasoline, E85, or any blend of the two at the pump without manual adjustments. The digital injector management contributes to increased horsepower and torque, with a proven gain of 7-8% wheel HP and torque on E85, which equates to approximately 40-45WHP. This system is compatible with stock or performance gas tunes and adapts instantly to new tunes.
