At Speedshop44, we specialise in precision tuning solutions, rolling road power runs, and advanced diagnostics tailored for modern classic vehicles 80s, to the early 2010s – covering ECU and carburettor-based classics. Whether you drive a high-performance, fast road vehicle, or race car, our expert team delivers performance and reliability through cutting-edge technology and a deep passion for classic engineering.

ECU Remapping & Custom Tuning

Optimise fuel delivery, ignition timing, and boost control to maximise horsepower, torque, and drivability. We provide bespoke ECU remapping and tuning tailored to each vehicle’s unique setup and modifications—ideal for modern classics that deserve peak performance.

Carburettor Custom Tuning

Use our rolling road to expertly tune classic road and race cars running SU, Weber, Dell'Orto, or Solex carburettors. We fine-tune fuelling and ignition for smoother power delivery, sharper throttle response, and performance that’s perfectly dialled in for road or track use.

Rolling Road Power Runs

Our in-house rolling road dyno delivers real-time, accurate performance data. Monitor horsepower, torque curves, and air/fuel ratios to precisely assess your car’s current performance—and see the gains from every tuning adjustment.

Advanced Diagnostics & Troubleshooting

Using state-of-the-art diagnostic tools, we detect and resolve engine management issues quickly and effectively. Whether it’s a fault code, misfire, or poor throttle response, our diagnostics ensure your modern classic runs as it should.

Sustainable Fuels

With expert tuning, we can optimise your classic car for modern fuels like bioethanol or synthetic alternatives. Once properly set up, modern fuels can offer cleaner combustion, increased power potential (thanks to higher octane ratings), and reduce environmental impact, making them a great option for future-proofing your performance vehicle.

Why Use a Rolling Road?

When it comes to extracting the best performance from your modern classic—whether it’s an Audi Quattro, Subaru Impreza, Ford Cosworth, Honda Civic Type R, or Porsche 911—precision is everything. At Speedshop44, we use a state-of-the-art rolling road (dyno) to provide the most accurate and reliable platform for tuning, remapping, power runs, and diagnostics.

Precision Tuning for Real-World Gains

Unlike traditional tuning methods, which rely on estimations or static conditions, a rolling road simulates real-world driving. This allows us to test and adjust your vehicle's fuel maps, ignition timing, turbo boost, and more—while under actual load and RPM, delivering accurate, measurable improvements in horsepower, torque, and engine efficiency.

Accurate Power Runs

Get clear, graphical proof of your car’s performance. Our dyno power runs measure wheel horsepower (WHP), torque curves, and air/fuel ratios, showing exactly how your engine setup is performing. Ideal for comparison before and after ECU remapping or mechanical upgrades.

Diagnostic Clarity

Struggling with performance issues? The rolling road helps us identify hidden faults under realistic driving conditions—things like fuel delivery inconsistencies, boost leaks, or misfires that might not appear during a static diagnostic check. This level of detail helps us fix problems faster and more effectively.

Data-Driven Remapping

All remaps at Speedshop44 are based on live data from our dyno sessions. That means no “one-size-fits-all” tuning—just custom, vehicle-specific remapping tailored to your modifications, driving style, and performance goals.

Perfect for Modified & Classic Performance Cars

Rolling road testing is essential if you've fitted:

Aftermarket turbos or superchargers
Performance cams or exhausts
Standalone or piggyback ECUs
Intake or fuelling upgrades

Without live dyno data, these upgrades can lead to poor drivability, underperformance, or even long-term engine damage due to incorrect fuelling or timing. A rolling road is essential for accurately calibrating how these performance modifications interact under real driving loads, ensuring the engine management system is finely tuned for maximum power, response, and reliability.
