Tuner Kits: These kits make sense for someone wanting to perform custom tuning and push the envelope in performance. These builds may include alternative fuels such as 93 octane, race fuel, E85, or methanol supplemental fuel, along with engine upgrades like heads, headers, exhaust, and camshafts. No tuning or fuel components provided.

Tuner kits are designed for customers who want the hardware package and plan to complete their own custom tuning and fuel system setup.
