Fitting Notes
- Bolts in on the factory mounts and hose locations.
- No tune is strictly required. A calibration can unlock more by optimising boost, fuelling and timing for the lower intake temps.
- Safe boost depends on your turbo, clamps, couplers and overall installation quality, not just the core rating.
