Trusted Mechanical is a diesel mechanic in Adelaide built on two pillars. We are a diesel-performance house with an in-house dyno: custom diesel tuning Adelaide owners trust, ECU remapping, 4x4 towing and touring tuning, the off-road DPF and EGR work and the legal DPF clean, plus ECU=Shop modules for locked ECUs.
We are also a trustworthy local workshop. As an RAA Approved Repairer we deliver honest servicing and log-book servicing that keeps your new-car warranty intact, with free loan cars, all work guaranteed, and a firm promise: we will not charge you for work you do not need.

Every performance tune is written and load-tested on our in-house chassis dyno. We see real airflow, fuelling and exhaust gas temperatures under load, then dial the map to your specific vehicle, rather than flashing a one-size file and hoping. Your factory map is saved first, so the tune stays reversible.
This is the difference between a result that is real and repeatable and a generic mail-order tune. See the diesel tuning hub or our 4x4 diesel tuning.
