FAQ

With proper fuel, air, and tuning, the 71mm S400-frame with a .90 A/R can support serious street/track power. Build limits depend on injectors, pump(s), intercooler, and engine health.

Yes. Calibrations should be revised for the fixed-geometry S400, wastegate strategy (if used), and airflow/fueling changes.

They're strongly recommended above stock boost or heavy towing/competition use. See ARP 247-4202 and 247-4204 options linked above.
