BMW G-Series Custom Tune

We can tune any configuration you have, the more complicated the setup the more we charge for tuning. Below are power figures and upgrade recommendations to get you started. Although we don't show STG1 Ethanol, or nitrous we support it. Ethanol puts a lot more demand on the High Pressure Fuel Pump. Running higher ethanol contents ultimately means you'll have to run lower boost pressure. Secondary injection will be the future of this platform once it becomes integrated and controlled by the factory computer.
