Viper X3 Module

We are proud to introduce our most powerful and newest Plug-n-Play self tuning Performance Tuner Chip. The Viper X4 Tuner Chip features advanced Stage 3 programming that perfectly balances power and torque. The Viper X4 Tuner Chip meticulously monitors and optimizes your vehicle's Engine Control System to increase performance and driving fun. 
This powerful plug in device connects to the OBD port of your vehicle. Once plugged in, it integrates with your vehicle via the OBD2 port. Viper X4 has access to all of your car's vital operating parameters. The Viper X4 Tuner Chip produces it's jaw-dropping results by specifically targeting Air/Fuel Ratio, Fuel Injector Pulse Width, and Ignition Timing, using our own pre-tuned engine maps. 
Air/Fuel Ratio - is constantly and continually adjusted to produce a smooth running engine with good power, high efficiency, and low emissions. Careful tuning here provides a very responsive engine. Additional horsepower is very easily felt and can totally rejuvenate your driving experience.
Fuel Injector Pulse Width - is used to control how much fuel is injected into the engine. During relaxed driving, less fuel is injected. The engine uses less fuel and mpg increases. During spirited or performance driving, more fuel is injected into the engine to create more power. Power production goes way up and the engine can move the vehicle with ease! 
Ignition Timing/Spark Advance - is optimized to carefully tailor the engine to current driving conditions. Adding Spark advance at low rpms, greatly increases torque production. This allows the car to accelerate briskly from a stop, up hills, and while carrying a load. The engine doesn't have to rev as high to produce the same level of power. At high rpms, ignition timing is refined even further to produce exceptional top end power. 

Custom Wiring and Programming - Ever wonder how the 'other guys' can offer a 'custom' chip for your vehicle without knowing your vehicle? Ours contains a real microprocessor - No Scams, just custom performance.
Superior Concept - The X4 has been engineered and built from scratch with premium design and components to be extremely reliable and powerful. Stop wasting money on scams that do not work. We are positive the Viper X4 is the best chip you will ever buy, and you will be extremely satisfied with the results. Our Custom tuning and programming provide the Viper X4 Tuner with great power output while barely affecting fuel economy... A true win/win.
Installation is extremely simple - The module simply plugs into the OBD Port under your car's dashboard. This port is usually near the steering wheel on the driver's side. Vehicles made from 1996 to present have this port.

Should you decide to uninstall the tuner, just unplug it and your vehicle goes back to its stock (factory delivered) state. This Tuner will leave no trace that it was ever installed. This makes it perfect for leased vehicles and rental cars that must be returned in factory condition.
