If your turbochargers arrive with wastegates fitted, do not use the supplied wastegate units — their condition and calibration are not guaranteed. Reuse your factory wastegates for known, reliable operation.
What These Turbos Need
Tuning is required; the factory calibration has no strategy for these turbos. The rest controls heat and airflow so the turbos deliver what they are capable of.
- Custom ECU calibration — required.
- Exhaust: catless downpipes or heat-shielded catless downpipes.
- Heat management: front mount + auxiliary heat exchanger bundle, CSF auxiliary radiators, turbo blankets.
- Intake: 3″ dual intake kit or intake filter spacer kit.
Core Return
- Core return required — remove your factory wastegate actuators before shipping
- The core deposit is fully refunded once acceptable cores are received
