GenTech Automotive & Performance Centre

GenTech Automotive & Performance Centre is a Holden and performance workshop in Mitchell, Canberra

​

GenTech Automotive & Performance Centre is a mechanical workshop at 3 / 34 Hoskins Street, Mitchell, in the Gungahlin district of Canberra, Australian Capital Territory. They specialise in Holden and high performance vehicles and in diesel tuning, and they also carry out the everyday work any workshop handles, from logbook servicing to brakes, air conditioning and auto electrical repairs. Marcus leads a team of mechanics with more than a century of combined experience between them, and the workshop is an ACDelco Service Centre.

​

What performance work do they specialise in?

​

Performance is where the workshop is best known. They build engines in house, including stroker engine builds, and they fit complete exhaust systems, cold air intakes and high flow induction. Engine management work covers ECU recalibration and LS1 Edit for Holden V8s, and they change differential ratios and upgrade brakes and suspension to match the extra power. The team takes the time to understand how a vehicle is actually used before recommending upgrades, so the result suits the driver rather than just the spec sheet.

​

What does their diesel tuning involve?

​

Diesel tuning is a substantial part of their work, particularly for utes and 4WDs such as the HiLux, LandCruiser and Patrol. They carry out custom ECU remapping that is dyno tested, adjusting engine settings for more torque, sharper throttle response and, in many cases, better fuel economy. Dyno testing means the result is measured on the workshop equipment rather than estimated, which matters when a vehicle is towing or carrying weight.

​

What general servicing and repairs do they do?

​

Alongside the performance side, GenTech handles logbook and warranty book servicing to keep a new vehicle warranty in place, plus general mechanical repairs across a wide range of makes and models. Their work includes transmission repairs and recalibrations, differential repairs, brake and suspension work, air conditioning service and repair, and auto electrical diagnostics and repairs. They inspect first and recommend only the work a vehicle genuinely needs.

​

What can customers expect?

​

Customers deal with the mechanics directly and are talked through the options and what each one will do, which suits both drivers wanting a straightforward service and owners planning a modified build. Loan cars are available for customers who need to keep moving while their vehicle is in the workshop.

​

What do they provide for fleet operators?

​

Fleet servicing and repairs are part of their regular work, covering scheduled servicing, mechanical repairs and diagnostics for work utes, vans and light commercials. For operators running diesel utes, the tuning side is available as well where a vehicle needs to work harder under load.
