Rhys embarked on an exciting road trip from the west side, driven by his passion for automotive performance and a desire to unlock the true potential of his Audi SQ5 TDI. His destination? A top-notch service center known for their expert walnut blasting and custom dyno tuning. What followed was an impressive transformation that exceeded all expectations.

Starting Point: Solid Performance

Rhys' Audi SQ5 TDI wasn't just any vehicle—it was already a powerhouse with a stock output of 201 kW and 560 NM of torque. While this might seem more than adequate for most drivers, Rhys knew there was untapped potential under the hood, and he was eager to see just how much more his car could deliver.

The Magic of Walnut Blasting

The first step in this automotive makeover was a walnut blast, a procedure that uses finely crushed walnut shells to clean the engine’s intake valves. Over time, carbon deposits can build up and restrict airflow, leading to reduced engine efficiency and performance. The walnut blast effectively removed these deposits, giving the engine a much-needed breath of fresh air. This procedure not only restored lost power but also improved fuel efficiency, making it a win-win.

Custom Dyno Tune: The Heart of the Transformation

With the engine freshly cleaned and primed, it was time for the custom dyno tune. This is where the magic really happens. By connecting the car to a dynamometer, technicians were able to measure its power output and make precise adjustments to the engine control unit (ECU). This process optimizes various parameters like the air-fuel ratio, ignition timing, and boost pressure to maximize performance.

The Results: More Power, More Thrill

The results were nothing short of spectacular. After the custom dyno tune, Rhys' Audi SQ5 TDI surged to a new output of 231 kW and 682 NM of torque. This significant boost transformed the car’s driving dynamics, providing more thrilling acceleration and an overall enhanced driving experience. The increase in power and torque was palpable, turning every drive into an exhilarating adventure.
