HAVE VEHICLE MODS? GET A TUNER KIT!

Tuner Kits: These kits make sense for someone wanting to perform custom tuning of the car and push the envelope in performance.  Will most likely be experimenting with alternative fuels such as 93 octane, race fuel, E85 fuel, and methanol supplemental fuel.  In addition, possibly changing engine components like heads, headers, exhaust, and cams for the engine. No tuning or fuel components provided.

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.

  • HO Tuner Kit – P/N 1GI202-SCI
  • Stage ll Tuner Kit – P/N 1GI502-SCI

 

*Higher boost levels are available for modified engines.
