A vehicle remap replaces default software on the ECU, overwriting it with new software which can be programmed to optimize the cars overall performance. This is known as vehicle remapping because the ECU is essentially a program that controls how the engine works. When your car is remapped, the tuned software is plugged into your cars serial port (or OBD port) which then overwrites the engine map with the new version to enhance engine performance. The ability to flash directly through the OBD has brought the tuning industry on leaps and bounds, with constant development on the engine now being much quicker via the flash process, it has enabled Elite Remap to develop some of the best software in the world.

Many automotive companies offer aftermarket exhaust system upgrades as a subcategory of engine tuning. This is often fairly expensive as it usually includes replacing the entire exhaust manifold or other large components. These upgrades however can significantly improve engine performance and do this through means of two main principles:

Spend the same money on a good quality suspension setup, and it's a different story. Shaving an inch or so off your ride height tucks your wheels a little closer to the arches for a concept car stance. It also brings your centre of gravity lower to the ground, reducing body roll and helping you corner better.
