How much horsepower will I gain?
Results vary depending on vehicle condition, fuel grade used, etc., but will be around 25+HP. The chip recalibrates the ignition and fuel based on the variables such as the fuel octane, ambient air temp and other sensors in addition to driving style.
Can this harm my engine or vehicle electronics?
No. Our products have been dyno tested and proven to work with no negative effects on the vehicle.
How does this product work?
It plugs into your ECU module, replacing the stock chip. The chip modifies signals sent to your vehicle’s ECU computer. It optimizes functions such as ignition timing, air fuel mixture, fuel maps and produces more power and better gas mileage. The ECU of modern vehicles controls many variables which ensure the best engine performance. It does this by reading values from a multitude of sensors within the engine bay, interpreting the data using multidimensional performance maps (tables), and adjusting the engine accordingly. It does this in real-time.
