Stage 1
A healthy standard vehicle will usually need no hardware changes before a sensible Stage 1 calibration.
Upgrade parts for your BMW X1
Hardware should be selected around the engine, fuel system, tuning stage and intended use - not from a generic parts list.
Stage 2
Intercooler, intake, exhaust and charge-cooling requirements are reviewed against this exact powertrain before quoting.
Custom builds
Turbo, fuelling, sensor and engine upgrades are assessed as one system so the calibration matches the fitted hardware.
