Did you know that you can essentially obtain the same effects of the "big name" power programmers without the expensive pricetag?  The power programmers adjust and rewrite your factory Engine Control Module directly. The main downside of these programmers is that they completely rewrite your factory Engine Control Module, the brain of your vehicle.  These power programmers leave several footprints and traces behind in the memory.  Did you know that many dealerships check for these footprints during normal servicing and could VOID your factory warranty since the factory Engine Control Module is being directly rewritten?

Our Tunesport Performance Modules carry absolutely NONE of those risks because our products do not directly access or rewrite your factory Engine Control Module.  The advantage of our modules is that they operate safely and efficiently.  If you ever wish to go back to your factory settings, you  simply uninstall the Tunesport Performance Module and your vehicle will instantly revert back to original factory specifications.
