IMI-Certified ECU Remapping & Chip Tuning Specialists

At Top Tuning, we specialise in professional ECU remapping to enhance your vehicle’s performance, fuel efficiency, and driving experience. Our IMI-certified experts fine-tune your vehicle’s software, ensuring it responds precisely to your bespoke requirements rather than factory-set limitations.

Advanced ECU Tuning for Maximum Performance & Efficiency

Our qualified technicians access your ECU’s stored map via the OBD (onboard diagnostics port) or through Chip Tuning (Bench Tuning) by physically removing the unit. Once we extract the data, we meticulously adjust key parameters to maximise power output, improve fuel savings, or achieve both.

Fast & Efficient Process – Minimal Downtime

The entire remapping process typically takes under an hour, depending on the vehicle and ECU type. Chip Tuning may take slightly longer but ensures precise performance optimisation for the best possible results.

Unlock your vehicle’s full potential with expert ECU remapping and chip tuning from Top Tuning.

Chip Tuning & OBD Remapping – Unlock Peak Performance

Chip Tuning is a specialised form of ECU remapping, where the actual programme chip is removed, re-programmed, or replaced with a new, performance-optimised version. While modern remapping techniques have largely replaced this method, Chip Tuning remains essential for certain vehicles, offering precise control over power output and efficiency.

OBD Remapping – Fast & Effective ECU Optimization

OBD Remapping is a highly efficient way to modify engine performance via the ECU (Engine Control Unit). Also known as OBD port tuning or OBD port remap, this technique enables seamless software adjustments to enhance power, torque, and fuel efficiency—all via the vehicle’s onboard diagnostics port.

Performance Remapping – Red Calibration for Maximum Power

For drivers seeking the ultimate in performance, our Red Calibration tuning delivers exceptional power gains while preserving manufacturer reliability and service intervals.

Our specialists provide expert ECU tuning for petrol and diesel vehicles, optimising: ✅ Torque Curve for Smoother Power Delivery ✅ Acceleration for Faster Response ✅ Heavy Load Running for Effortless Performance

Unlock your vehicle’s true potential with Chip Tuning, OBD Remapping, and Calibration Performance Upgrades.

Mobile Off-Car DPF Cleaning – We Come to You (12-Month Warranty Included)

At Top Tuning Limited, we provide professional mobile off-car DPF cleaning services across Wiltshire, Bristol, Swindon, Gloucestershire, Bath, and the surrounding areas.

Using advanced industrial DPF cleaning technology, we restore diesel particulate filters (DPFs) to near-new condition — improving performance, reducing backpressure, and helping you avoid the high cost of replacement.

✅ Same-day turnaround
✅ Over 98% of soot and ash removed
✅ 12-month warranty included
✅ We come to you — no more sending DPFs away for repair
✅ Work with our approved DPF centres for diagnostics, removal, and refit

You can either use your own trusted mechanic, or contact one of our approved DPF centres, who will take care of the diagnostics, removal, and refit for you. We then carry out the cleaning directly at the garage or workshop where the DPF is removed, or you can bring the filter to our base in Chippenham, Wiltshire.

DPF Cleaning Prices

£300 (inc. VAT) – Mobile service: we come to your garage, workshop, or dealership
£250 (inc. VAT) – Drop-off service: bring your DPF directly to us in Chippenham

Our DPF Cleaning Process

Diagnostics & Removal – Choose one of our approved DPF centres for full diagnostics, removal, and refit, or use your own mechanic.
On-Site Cleaning – We clean the filter at the same garage or workshop where it is removed, or you can bring it to our Chippenham base.
Endoscope Inspection – Internal and external inspection to check for cracks or damage.
Pre-Clean Back-Pressure Test – Measure current flow and blockage level.
Industrial Cleaning – Deep clean removes more than 98% of soot and ash deposits.
Drying Cycle – A high-volume airflow process is used to reduce moisture inside the filter.
Final Inspection – Filter is checked for cleanliness and structural integrity.
Post-Refit Care – Once the DPF is refitted, take an approximately 15-minute drive to allow any remaining moisture to fully evaporate. A diagnostic tool is then used to reset the ECU and confirm a clean/new DPF is fitted.
12-Month Warranty – Every clean is backed by a full year of peace of mind.
