ECU remapping will not only improve the engines power and torque figures it will also sharpen the throttle response and widen the power-band. This will make the power delivery a lot more linear, which in turn will make the vehicle feel a lot livelier to drive and the engine more flexible.
The other main benefit of remapping will be a reduction in fuel consumption. With the extra torque especially at the bottom of the rev range you will see a fuel saving as it will require less throttle input to maintain motorway speeds, you can drive in a higher gear at a slower speed as well as helping significantly when fully laden, towing or on gradients and even in start stop traffic.
ECU Tuning Benefits for Turbocharged Diesel Engines
Many see the modern crop of Turbocharged diesels as the future of road car tuning. Even in North America, a nation famed for its love of the petrol engine is starting to come around to the benefits of turbo diesel passenger cars in particular. These engines offer fantastic potential for reliable low cost tuning without removing any of the appeal of buying and running a turbo diesel powered vehicle, such as economy, reliability and longevity.

ECU Tuning Benefits for Turbocharged Petrol Engines
Turbocharged petrol engines have always been regarded as the sports flagship engine for good reason.
They boast far higher power & torque figures than a non-turbocharged power-plant with similar displacement and are usually fitted to the manufacturer's flagship models. They are also ideal candidates for remapping as the ECU also controls the wastegate (turbo boost pressure control).

ECU Remapping Benefits for Non-Turbocharged Petrol Engines
The normally aspirated petrol engine, whilst not being the easiest of engines to tune, can still benefit from a 10-15% power increase with added torque by careful reprogramming of various engine parameters within the map. Parameters such as the fuel and ignition curves can be fine tuned to give better power & torque output. On some engines the camshaft timing can also be tuned within the map, giving additional improvements. In many cases, 'after market' tuning items such as freer flowing exhausts, high flow air filters and re-profiled camshafts can only be fully utilised by the engine once the necessary adjustments have been made within the ECU. Careful recalibration of the correct maps can unlock the potential of your new engine parts. Further power gains may also be available when a higher octane fuel is used, allowing for more ignition timing.
