Frequently Asked Questions


Do I need any special tools or automotive knowledge to install?

No! the Xtreme Chip  is 100% plug and play. It is tuned for your specific vehicle make and model. Beware of for cheap $10-50 mega horsepower products. They are fake and are a plastic box with a .10 cent resistor.


Does this product work with automatic and manual transmissions?

Yes – Both.


Does this product work with 2WD or 4WD?

It works on both types if your car has options.


Will this product void my warranty?

No it will not void your warranty, many dealers frown on performance upgrades. However, the manufacturer cannot void your warranty for adding aftermarket parts.


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. We guarantee this!


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.
