How much power could you gain from a remap?


Car tuning by ECU remapping is a short-term investment built for long-term gain. At GAD Tuning, we specialise in the enhancement of high-end, high-performance brands and models so as to guarantee they are reaching their full potential when you are on the road. Whether it’s an ECU tune for your E63s AMG Mercedes, BMW or Audi, or even a Porsche, Ferrari or Bentley, our vehicle tuning service will help maintain the quality of motoring that your vehicle already embodies. That feeling of knowing your engine is running at the pinnacle of its powers is one that is rarely rivaled, and with an engine remap from our 4wd rolling road equipped workshop in Essex you can guarantee that will be the case every time you set foot in your supercar. What makes us stand out from our competitors? Our in-house team ensure each and every development is tailored specifically to the requirements of your vehicle thanks to our cutting-edge technology. The state-of-the-art communications equipment we have here at GAD Tuning mean that our Essex and London ECU remapping services can be carried out to the highest standard. Many companies will simply remove the maps and then install generic software that prevents you from accessing the full benefits that our ECU remapping center in Essex can offer, meaning your Lamborghini, Bugatti or any other sports car may never fulfill its full potential.
