Tuning Process

1. The engine is cleaned externally as required so we can access the components without contaminating the fuel system or internal parts.
2. We connect your vehicle to test equipment which checks:
   • Pump pressure and return flow
   • Injection Timing and Tachometer
   • Smoke emissions
   • Boost Pressure
   • Exhaust Back Pressure
3. Your vehicle is run on a 2wd or 4wd dynamometer to simulate road conditions and to view a readout of your vehicle’s performance prior to tuning. This allows for comparison of the before and after results.
4. We analyse the data, estimate tuning costs and give you a call to discuss your vehicle condition before work commences.

The technician does valve adjustment, filter changes, injector bench-testing, glow plug testing, and reset of the injector pump timing to the manufacturer’s specification. Any shortfalls in automatic advance systems and pressures are rectified as required. We reset turbocharger pressure to original specifications (if required and applicable). Then, the boost/fuel compensator housing is cleaned out and set to the correct specifications.




5. Your vehicle is run on the dyno again. This gives us an overlapping “after tune” read out to compare the results.
