The most common of all tuning questions. It is not complicated but there are a few answers to this question, some more obvious than others.

Vehicle manufactures are in a tough position here, they have to build one vehicle for all drivers – it’s a bit like a nice suit off the shelf; it fits well, it looks smart, but it can’t be custom tailored for the end customer. Tuning is just the same – if you own a fleet of vans you may want a speed limiter or rev limiter added to help save your fuel, yet another customer may want a little more power to help with towing or heavy payloads. These sorts of changes can only be made once the vehicle is built and the customer needs something other than ‘off the shelf.’

Fuel quality – we are often asked to tune for different fuel quality, either higher or lower. Once an owner knows where his vehicle will be used and what it will be used for we can adapt the tuning for environmental, altitude and fuel quality.

In addition, many manufacturers offer power and performance tuning upgrades too, or offer the same engine in a range of vehicles offering different power levels. This enables customers a choice, taking account of tax banding, insurance, performance, price and economy. In most cases though the choice is controlled with software just like our tuning, but with Eagle Tuning you don’t have to decide what you want from new in the showroom, we can tailor your vehicle to your needs whenever you want.

No. A remap or any aftermarket work cannot and will not automatically invalidate a vehicle’s warranty. It’s a misconception that it will, and sometimes those that know are not always clear about this fact. It’s very common for fleet users and companies to fit a speed limiter to their vehicles. Some will use us to do this work, while other drivers may want to fit a tow-bar or upgraded sound system to their vehicle. These are common fitments, but they are aftermarket changes just like a remap – your tow-bar does not invalidate your warranty so why should you remap?

However, manufacturers of course have the right to investigate and possibly reject a warranty claim if the failure is directly related to and caused by the tuning (remember not all tuning is the same quality as Eagle tuning). Therefore, for your total peace of mind, all Eagle tuning work is insured and guaranteed. If our tuning causes a failure inside or outside of the warranty period you are covered. It’s exactly why you should choose Eagle for all your tuning.

Should you lose your tuning files due to dealer actions or parts failure we will be happy to re-install the map onto your car free of charge for as long as you own the vehicle.

There are a number of basic power upgrades available in a plug-and-play format or are downloadable from the web. Whilst some of these items can offer slight increases in power, they operate by merely adjusting a specified signal within the ECU by a set tolerance. It’s impossible to compare these inferior upgrades with a full rolling road re-map which measures and adjusts hundreds of signals and data files within the ECU.

We advise that these generic files and unsupported devices for sale on the web should be avoided at all costs. We’ve seen too many customers come to us after a bad experience – and there was no one else to turn to either. We’re always happy to advise on your tuning needs.

No, not at all if you use a Eagle tuning. Sadly some engines can be over-tuned, ‘stressing’ the engine, transmission, cooling systems, brakes, etc, and reducing the life span and reliability of the car. This is why it’s so important to choose the best. Choose Eagle – the research and development we carry out to ensure all our tuning is of the very highest standard possible.

We take great care to ensure that all of our modifications have no detrimental effect on your car. In a lot of cases, the economy tune actually helps to extend the life of components, such as the clutch and gearbox, by making the delivery of the power far less aggressive and smoothing the overall drive of the vehicle.
