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 22+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.
