FAQ
Fitment is confirmed for the applications listed in the Specs section above. Always confirm final fitment by year, market, and supporting hardware before ordering.
Yes. A professional calibration is required to safely control boost, fueling, torque limits, and thermal management.
Fueling, charge-air cooling, intake flow, downpipes, and drivetrain upgrades may be required depending on target power and fuel type.
The system is engineered for strong response, but daily drivability depends on calibration, fuel quality, supporting parts, and installation quality.
Warranty coverage applies to manufacturing defects under normal installation and operating conditions. Track use and improper calibration may affect coverage.
