WHO ARE WE?
DIESEL PERFORMANCE EXPERTS
GSL is a family owned Australian company who excel in Diesel Performance. We hold the Australian record for the fastest Land Cruiser, 4JJ1 and plenty more.
Almost all of Australia's most well known Diesel's use our systems. (Frankenmule, Mega 6x6, Black Truck etc.)
FULLY CUSTOM IN-HOUSE TUNERS
One of our most highly requested services is our fully tailored ECU remaps.
Unlike many tuners who just use a slave tune, we custom fit your tune to your needs, whether it's performance, towing power, or fuel economy, we'll make sure your rig will give you the best it has to give.
THOROUGH PRODUCT TESTERS
In order to test out the quality of our products, we first get them tested for compliance towards legal standards, and then we'll test them on our personal cars to make sure they're as good as can be.
Our experience in the Drag racing scene helps us find just how much our products can take.
