The DINANTRONICS Elite Performance Tuner is a highly engineered piece of computer hardware and software that enhances engine performance to levels the stock programming is not allowed to venture into. It does this without negatively affecting your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It is also the only tuning device designed to be emissions legal in all 50 states. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful reliable and warrantied package. The Dinan Difference is possible by employing a full staff of talented engineers that are well rounded in many facets of automotive engineering and backed by a wealth of hands-on knowledge. Stemming from diverse backgrounds not only on racing teams but on standard factory production line vehicles we have seen it all. Manipulating these signals with an adept hand all the while keeping an engine running at its best and with the most reliable power is what Dinan is all about.
