Why Choose Tunesport Performance for your GMC?

The Tunesport Performance Module is the answer to increasing your GMC's performance and getting the most fuel economy out of your engine. The Tunesport Module calculates the correct combinations of air, fuel and spark to produce more power, unlocking up to 30 Horsepower and up to 8 MPG in your GMC*! The Tunesport Performance module is designed to work with both stock and modified GMC engines, manual and automatic transmissions, turbochargers, superchargers, gas, diesel and turbo diesel engines.

Our technical support and customer service is unrivaled and will be here for you every step of the way! We offer free support and can provide GMC model specific information to aid in installation, unlike our competitors. Your order will include everything you need to install your Tunesport module on your GMC. Installation is very simple and anyone can easily install our module within 5-10 minutes!

Our Tunesport module will alter your air/fuel ratio without leaving any footprints/traces behind in the memory. Many dealerships check for these footprints during normal servicing and could VOID your factory warranty. Our Tunesport Performance Modules carry absolutely NONE of those risks because our product does not reprogram your ECU and does not make changes that you do not want or understand. Our modules operate safely and efficiently, never pushing your engine past factory safety limits which could damage your engine/transmission. If you ever wish to go back to your factory settings, simply uninstall the Tunesport Performance Module and your vehicle will instantly revert back to original factory specifications without any trace.
