HAVE VEHICLE MODS? GET A TUNER KIT!
If you have, or plan to add in the future, other vehicle modifications, like experimenting with alternative fuels such as race fuel, E85 fuel, and methanol supplemental fuel, or changing engine components like heads, headers, exhaust, and cams for the engine, then a Tuner Kit is the best option for you. These kits make sense for someone wanting to perform custom tuning of the car and push the envelope in performance.
Tuner Kits are identical hardware to full systems, except they do not include tuning or fuel components. Tuner kits are highly customized by the end user and are, therefore, not emissions certified.
