E85 Flex Fuel System

The Advanced Fuel Dynamics PFC-GMS1 is a game-changing upgrade for 2009-2013 V8 Chevrolet Tahoe, Suburban, and GMC Yukon owners. This Plug and Play Active E85 Flex Fuel System simplifies the use of E85 fuel, offering enhanced performance without the hassle of complex tuning or modifications. The system is designed for a 1-hour DIY installation using common tools and works with stock induction and injectors, eliminating compatibility concerns. Key features include patented BlendSense™ technology that adjusts in real-time with a 30-millisecond refresh rate, providing true flex fuel capability to switch between gasoline and ethanol seamlessly. The system has been 100% dyno tested for safety, durability, and power gains. It offers 7-10% more wheel horsepower and torque on E85 and improves injector management for better performance on both gas and E85. Additionally, it promotes cleaner emissions and cooler engine temperatures, while Cold Start Plus™ technology enhances fuel atomization for easier cold-weather starting. This system is compatible with stock or performance gas tunes and instantly adapts to new tunes. It is suitable for stock or lightly modified vehicles running factory fuel injectors and naturally aspirated setups. For vehicles with aftermarket forced induction or larger fuel injectors (600cc / 60 lb/hr or bigger), the Commander Pro version is recommended. Fitment includes Chevrolet Tahoe V8 4.8/5.3/6.0/6.2L (2009-2013), Chevrolet Suburban 1500 & 2500 V8 4.8/5.3/6.0/6.2L (2009-2013), and GMC Yukon & Yukon XL 1500 & 2500 V8 4.8/5.3/6.0/6.2L (2009-2013).
