Frequently Asked Questions

How do I choose the correct injector size?
Injector sizing depends on horsepower, fuel type, base fuel pressure, cylinder count, and target duty cycle. Confirm the calculation and exact injector data with the tuner before ordering.

Can Grams Performance fuel components be used with E85?
Compatibility depends on the exact part and the complete fuel system. Confirm the injector, pump, seals, hose, filter, rail, regulator, and manufacturer guidance for the intended fuel.

Do injectors or electronic throttle bodies require tuning?
Fuel injectors require the correct characterization data, and drive-by-wire throttle-body requirements vary by application. Confirm ECU support, calibration, and safe startup procedures with the tuner before installation.
