Another day, another Fuel Wars! video! This time, we strap @trail_command's long travel supercharged V8 Tundra to the dyno and let it rip.
All gains seen in this video are strictly from swapping fuel. The eFlexFuel system automatically adjusts fueling for the exact ethanol blend in the tank and extracts performance from E85’s chemical properties.
The formula is simple: No tuning, no permanent modifications required. Simply install an eFlexFuel kit, fill up with E85, and make more power!
eFlex + E85 Vs Gas Results
- +44.23 Wheel Horsepower max gains under the curve with E85. That’s an 11.4% increase in WHP!
- Peak gains of +39.11 WHP
- HP Gains were observed across the entire powerband.
- All gains achieved instantly by filling up with E85 with an eFlex kit installed. Zero ECU flashing or tuning involved.
