HORSEPOWER IS GREAT, BUT HOW DOES IT DRIVE?
Over two years of engineering, testing, and refinement went into the ProCharger supercharged C8 Corvette PCM calibration. Our test cars and our staff tackled extreme conditions, from 126-degree summer in Death Valley to -4-degrees in a Midwest winter. All to ensure the quality, safety, reliability of the calibration and custom operating system (OS).
This OS gave 100% control over the PCM, allowing engineers/calibrators to write new tables, add features, and add safety functions specific to forced induction for both the engine and the transmission, none of which are present in the stock C8 PCM.
Features such as…
- Exclusive factory clutch protection protocol
- Exclusive user selection for DoD/AFM activation
- 3bar boost aware airflow/torque modeling
- Fan system cal to control intercooler temp
- Intercooler air temp added and monitored
- Full diagnostic for all modified/added sensors

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.
STAGE II TUNER KIT
Same as Stage II System except:
• Custom boost level and head unit options
• Does not include tuning, fuel system
• For modified engines and exhaust
• Part #: 1KC602-SCI
