About Tunehouse

Tunehouse is a Sydney-based performance workshop specialising in wide span vehicle servicing, maintenance and performance enhancements, with particular emphasis on late model vehicles. We offer all types of automotive services in Sydney, and are well known within performance, fleet servicing and automotive circles in Australia.

Tunehouse technicians can provide you with a one stop shop for servicing and repairs to carry out manufacturer’s handbook services without losing your new car warranty.

Tunehouse is led by managing director/owner, tuner and head diagnostician Jim Ghelis. Jim boasts over 25 years of trade, race and tuning knowledge grafted from real experience, study and research – both locally and internationally. The combined knowledge base and clinical workshop practice is what gives Tunehouse more than just an edge over the competition.

“Performance motor sport engineering encompasses an ability to produce, modify and create vehicles of a high calibre. Synonymous with this is an ability to then demonstrate the potential of this performance work on the race-track.”

Tunehouse exemplifies this ethos and carries this philosophy through to basic servicing and customer service. Tunehouse delivers outstanding service, performance and reliability in every aspect of its business and trade practice.
