Frequently Asked Questions
Q: Can I daily-drive with 500% over injectors?
A: These are intended for race builds. Drivability and emissions compliance will require careful setup, and street use is not recommended.

A: Yes—pair with a high-flow Exergy CP3 (10–14mm) and a quality lift pump to maintain rail pressure at WOT.
Q: What tuning is required?
A: Custom calibration for pulse width, timing, and rail pressure is essential. Plan for data logging and iterative revisions.
Q: What’s the warranty?
A: Covered under Exergy’s manufacturer policy; follow install best practices and provide clean fuel to maintain coverage.
