About UPSPEC Performance

Evolving from an enthusiast beginning in 2012 under the name Intense Performance Tuning, UPSPEC Performance (aka UpSpec Garage) was the ECU Tuning authority behind The Rumble Shack, a Sydney-based Subaru Specialist workshop incepted in 2016. For over 8 years, we provided our expertise to a wide range of Subaru vehicles from daily drivers to race track warriors, and some projects pushing up to 500KW at the wheels.

On January 25th, 2024, we concluded our tenure at The Rumble Shack, marking the end of a significant and rewarding chapter. We have since established our own dedicated workshop, where we not only continue to offer specialised performance solutions but have also expanded our capabilities to provide a full range of mechanical services for Subaru vehicles.
