Flex-fuel tuning needs precise ethanol content. Blend pump E85 with regular gas (E10) to hit a target ethanol percentage, or reverse it — tell us your mix and see the actual ethanol level plus fuel-flow needs.
Ethanol cools intake charge and resists knock — great for boost.
Handles summer and winter E85 blends plus E0/E10 base fuels.
Higher ethanol needs more fuel — see if your injectors keep up.
