From the hypertech site........

For the purposes of improved air quality, availability of Reformulated gas (RFG) is being required in some parts of the country. Hypertech is including Power Tuning for select vehicles using this gasoline, sometimes called "oxygenated fuel". We encourage our customers to identify the type of gasoline being used and select the Hypertech Power Tuning accordingly.
