Rolling Road
Know your true power figures.
Our chassis dynamometer gives you real, measurable power and torque data. No guesswork. No inflated claims. Just honest figures you can trust.
A rolling road session at Wallace Performance puts your car on our calibrated dyno to measure wheel horsepower, torque curves, and air-fuel ratios in a safe, controlled environment. It is the only way to know for sure what your car is making. We use the data to validate tuning work, spot mechanical issues, and provide a baseline for future modifications. Every session includes a printed dyno graph and a full verbal walkthrough of the results. Whether you are chasing more power or just curious, a dyno run is an essential part of any performance build.
What's Included
Calibrated 4WD-capable chassis dynamometer
Wheel horsepower and torque measurement
Air-fuel ratio monitoring via wideband O2 sensor
Pre- and post-modification comparison runs
Boost pressure and intake temperature logging
Printed dyno graph with peak figures
Safe, controlled testing environment
Expert interpretation of results included
Our Process
Pre-Dyno Inspection
We check fluid levels, tyre condition, and straps to ensure your car is safe for a power run.
Baseline Power Run
The first run establishes your current power and torque figures across the full RPM range.
Data Logging
We log air-fuel ratios, boost pressure, and temperatures to assess engine health and tuning accuracy.
Analysis and Report
Our technician talks you through the graph, explaining what the numbers mean and flagging any concerns.
Recommendations
If your car is not making what it should, we advise on the next steps — whether that is a remap, an upgrade, or a repair.

ECU Remaps
Most engines are deliberately detuned from the factory. Our custom ECU remapping safely releases that hidden power and improves the way your car drives.
Custom Exhaust Systems
Off-the-shelf exhausts are a compromise. We design and build custom exhaust systems that fit perfectly, sound exactly how you want, and deliver real power gains.
Fault Diagnostics
Modern cars are controlled by dozens of computers. When something goes wrong, you need the right tools and expertise to find the root cause quickly. Our diagnostic service goes far beyond a simple code read.
What Our Customers Say
Real feedback from real drivers who trust Wallace Performance with their cars.
"Wallace Performance remapped my Astra and the difference is night and day. Throttle response is instant, power delivery is smooth, and the car pulls hard right to the redline. They even did a before-and-after dyno run so I could see the numbers. Honest, professional, and seriously know their stuff."
Sarah Jenkins
Vauxhall Astra VXR Owner — ECU Remaps
"I brought my M3 in for a full geometry setup before a track day. The laser alignment was incredibly precise and the car felt completely different on the road — sharper turn-in, more stable under braking, and tyre wear has been perfectly even since. Worth every penny."
Michael Davies
BMW M3 Competition Owner — Laser Wheel Alignment
"Had a custom exhaust built for my ST and it sounds absolutely perfect. Not too loud on the motorway, but when you put your foot down it turns heads. The fabrication quality is top notch — TIG welds are beautiful and it fits like a glove. Wallace Performance is now my go-to garage."
James O'Connor
Ford Focus ST Owner — Custom Exhaust Systems
"My TT had a persistent check engine light that two other garages could not figure out. Wallace Performance diagnosed it in under an hour — a faulty coil pack and a dodgy sensor. They fixed it same day and the car has been faultless since. Proper diagnostics, not guesswork."
Emma Richardson
Audi TT Owner — Fault Diagnostics
"Rolling road session was brilliant. The dyno graph showed exactly where my power was dropping off and the team explained everything in plain English. We tweaked the boost and fuelling on the spot and gained 23bhp. You can't argue with printed proof."
Tom Bradley
Subaru WRX STI Owner — Rolling Road
"After lowering my Golf, the handling felt vague and my tyres were wearing unevenly. The four-wheel alignment sorted it completely. They set custom geometry for my coilovers and gave me a before-and-after printout. Car drives like it is on rails now."
