FAQ
Common questions
- Will high flow cats trigger a check engine light?
- We tune out any CEL issues related to the high flow cats. The tune includes proper O2 sensor calibration so you won't have any warning lights.
- Can I upgrade to RZ Stage 2 later?
- Yes. Your intake and cats carry over. RZ Stage 2 adds cooling upgrades and headers with a re-tune. You're not wasting money starting here.
- How long will my car be with you?
- Typically 2 days. Day 1: inspection, hardware install. Day 2: live tuning session, final validation runs, road test.
