The G-Box Gold Series works on the same premise as the original G-Box. However the Gold Series module utilizes a more aggressive set of operating parameters. 

The module functions by intercepting sensor outputs, modifying them, and outputting them to the vehicle's onboard computer. Even though the parameters of the Gold Series module are more aggressive than those of the original G-Box, most users are still able to attain significant performance gains without the use of premium fuel. 

The Gold Series module is also compatible with most popular performance upgrades such as aftermarket intake, exhaust, and ignition systems, low boost forced induction systems, lightened and/or underdrive pulley kits, grounding kits, and many others. We strive to acheive the highest standards of quality, while maintaining the best horsepower per dollar ratio in the industry. 

Simply put, Next Level performance modules are the best "bang for the buck" you will find.

Fuel Curve Basics.
Air/fuel ratios in modern automobiles are regulated by an Electronic Control Unit (ECU). Most factory ECUs are set to maintain a 14.7:1 air/fuel ratio; this is known as a stoichiometric fuel mix. This mix is a balance between power and fuel economy, which is what most automobile buyers are happy with. In general, leaning out the air/fuel ratio will cause a power loss and fuel economy gain; conversely richening the air/fuel ratio will cause a slight (usually less than 1/2 mpg) reduction in fuel economy and an increase in power. Generally the air/fuel ratio must remain between 13:1 and 17:1 to remain efficient, any leaner and the engine will be starved for fuel, any richer and the engine will not be able to combust all of the fuel causing inefficiency. Our modules increase performance by adjusting these ratios between 13 and 14.7, the more performance oriented fuel curves. Spark timing is also adjusted accordingly.

About the G-Box Gold.
The G-Box Gold Series enhances performance in multiple ways. 

First, it modifies signals being read by the ECU, causing an adjustment to the fuel curve, which is what creates the increase in horsepower and torque, as well as improves throttle response and shift speed. When the ECU sees these modified signals it provides a different set of fuel and ignition maps than it would under factory operating conditions. 

A second feature of the G-Box Gold Series is it's "High-Heat Signal Correction." In short, when the engine compartment heats up, some sensors that relay pertinent fuel curve contingent information to the ECU begin to lose accuracy due to heat absorption into the sensor. The ECU then reads these incorrect signals, and leans out, or otherwise incorrectly alters the fuel curve, which hampers performance.

These errors cannot be corrected from within the computer, there must be an independant unit to correct these errors. The G-Box Gold is designed to automatically compensate for these signal errors. Additionally, our easy to follow, step-by-step instructions will allow installation of your module in about 15 minutes.
