  • Economy (Eco) Maps: Specifically designed to improve MPG and reduce the carbon footprint of vans and motorhomes.

Performance Hardware & Upgrades

Software is only half the story. We supply and fit high-performance hardware from the world's leading brands:


  • Exhaust Systems: We are specialists in Milltek stainless steel exhausts.
  • Induction & Cooling: High-flow performance filters from ITG and K&N, plus uprated intercooler kits.

Performance vs/ Economy: Which is right for you?

Performance Tuning:


When manufacturers build a vehicle, they often "detune" the engine to account for global markets with poor fuel quality or varied climates. Performance tuning recovers this lost power safely.


  • Substantial BHP & Torque Gains: Experience a significant boost in horsepower and pulling power across the entire rev range.
  • Sharper Throttle Response: Eliminate "turbo lag" and enjoy a more linear, immediate response when you press the accelerator.
  • Smoother Power Delivery: Our maps ensure power is delivered smoothly, making the car feel more refined and capable during overtaking or merging.
  • Safe Limits: We only use software from DNA and JFA Tuning, ensuring your engine and transmission remain within their safe mechanical tolerances.


A performance remap is ideal for driving enthusiasts, towing heavy trailers/caravans, and anyone looking to breathe new life into their vehicle.

Economy Tuning:


With the rising cost of fuel, Economy (Eco) Mapping is our most popular service for fleet owners, van drivers, and motorhome enthusiasts. We focus on optimising the engine's efficiency to lower your pence-per-mile:


  • Improved MPG: By optimising fuel injection timing and boost pressure, most vehicles see a 10-15% improvement in fuel economy. 
  • Enhanced Low-End Torque: We increase torque lower down the rev range. This allows you to reach cruising speeds faster and stay in a higher gear for longer.
  • Reduced Carbon Footprint: A more efficient engine burns fuel more completely, resulting in lower CO2 emissions and a cleaner internal engine.
  • Return on Investment: For high mileage drivers, an Eco Remap often pays for itself in fuel savings within the first few months.


An economy remap is ideal for delivery vans, motorhomes, commuters, and fleet managers looking to reduce overheads.

Unlike mobile tuners, we are a fully equipped workshop. We use professional diagnostic tools from Autel, Launch  and Snap-On  to ensure your vehicle is in perfect health before and after the remap.

  • Does a remap affect my insurance?

    We always recommend informing your insurance provider of any performance modifications. Many insurers now view "Economy Maps" favourably.

  • Will it damage my engine?

    No. Our DNA and JFA maps stay within the safe mechanical limits of your engine and transmission. We prioritise reliability as much as power.

  • How long does ECU tuning take?

    Most remaps are completed within 1-2 hours. You are welcome to wait in our reception with a free coffee while we work.
