ECU Remaps
Unlock hidden performance safely.
Most engines are deliberately detuned from the factory. Our custom ECU remapping safely releases that hidden power and improves the way your car drives.
Wallace Performance writes custom ECU maps developed on our rolling road. We do not use generic off-the-shelf files. Every remap is tailored to your specific engine, fuel type, and modification level. The result is more power, sharper throttle response, smoother delivery, and in many cases better fuel economy. We offer Stage 1, Stage 2, and custom race maps. All work is fully reversible — we keep your original file on file so your car can be returned to stock at any time. Before and after dyno runs are included with every remap.
What's Included
Custom dyno-developed maps — no generic files
Stage 1, Stage 2, and custom race calibrations
Increased power and torque across the rev range
Sharper throttle response and smoother delivery

Our Process
Baseline Dyno Run
We dyno your car in stock form to establish a power baseline and check engine health before any tuning.
ECU Reading
Your original ECU file is safely read and backed up to our secure server before any changes are made.
Custom Map Writing
Our technician writes a bespoke calibration based on your engine, modifications, and driving goals.
Post-Tune Dyno and Road Test
The new map is verified on the dyno and then road tested to ensure smooth, safe performance in all conditions.
Handover and Support
You receive dyno graphs, a full explanation of the changes, and ongoing support if you need adjustments.

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."
