Frequently Asked Questions



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

  • No! Unlike the competition which requires you to cut wires, the Xtreme Chip  is 100% plug and play.
  • It is tuned for your specific vehicle make and model. 
  • Watch out for cheap $10-50 mega horsepower products. They are all fakes and are basically a 
  • plastic box with a .10 cent resistor, if that.


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 and can sometimes take up to 2 weeks to appear due to computer learning.
  • 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.
