Glen Mollee

Owner and Diesel Fitter

We at GSM Diesel Tune are committed to providing a top-level service to you.

With over 20 years’ experience in repairing, servicing and tuning all types of marine, on highway trucks, off highway mining equipment, tractors, heavy earth moving and 4X4, there’s not too much we haven’t worked on.

Some tunes may not be legal for street use in all Australian states. It is the client's responsibility to ensure that what they ask for is permitted.
