Vehicle Health Check\u003c\/strong\u003e\u003cbr\u003e\nBefore the car touches the dyno, we inspect the engine's current condition.

Custom Dyno Calibration\u003c\/strong\u003e\u003cbr\u003e\nWheels off the ground, strapped to our Mainline hub dyno. We build your calibration from scratch, adjusting fuelling, boost, ignition timing, and cam phasing to suit your specific engine condition and modifications. A 40,000 km engine is not the same as a 200,000 km engine, and we tune accordingly. Every value is monitored and logged. Faults are checked after every single run.\u003c\/p\u003e\n\n\u003cp style=\"font-size: 15px; line-height: 1.7; margin-bottom: 25px;\"\u003e\u003cstrong style=\"color: #BF1E2E;\"\u003e3.
