What changes can I expect?

• Improved fuel mileage of up to 5-6 MPG in gasoline engines and up to 11 MPG for diesel engines.
• Typical horsepower gains expected will be between 15-30% for gasoline engines (without switching to premium), and diesel engines can be 50% or higher!
• Throttle response rates on the vehicle will noticeably increase.

• No. Fuel requirements are custom programmed to your preference. However, with an aggressive tune you will experience a greater increase in power with premium fuel.

• No. In fact, the engine will usually run cooler when properly optimized, resulting in increased engine life.
