Good To Know

Q: Will I need a custom tune after installing a Stage 3 cam kit? A: Yes, a Stage 3 cam kit significantly alters airflow characteristics, so you must reprogram the ECU with a performance tune to ensure safe air-fuel ratios and proper idle control.

Q: Can I reuse my stock torque converter with this kit? A: While the stock converter may work, many Stage 3 setups benefit from a higher-stall torque converter to improve idle and off-idle response, so check the cam spec card for recommendations.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
