Engine Tuning

Remapping involves reading and tweaking the vehicle’s standard parameters such as fuel pressure, boost pressure, ignition advance, and throttle pedal control – amongst others – to release the true performance of the engine.

Should I Remap?

Is it safe to tune the ECU? Is it worth it? Here are the questions we get asked on a daily basis and the quick and easy answer is yes. Remapping your vehicle is a great way to get the best out of your car with no downsides. An ECU remap will increase horsepower, performance and optimise the vehicle for efficiency.

Another question that pops up a lot is can a remap damage your engine? The answer is no, not if done correctly by professionals. A remap can place more strain on the engine however here at South Coast Tuning we remap safely within the engines limits meaning your engine will be perfectly safe.

Can my car be remapped?

Probably. We can tune most vehicles built after the year 2000, and Diesels respond particularly well to a ECU remap. Get a quote today or if you have an older vehicle we still recommend getting in touch and speaking to one of our experts.

0% Finance Available!



Will a remap effect my insurance?

We would strongly recommend that you inform your insurer of any modifications you make to your car. Most would consider a remap as a car modification. You may see an increase in your insurance premium if you decide to go ahead with remapping your vehicle.

Will the Remap make my vehicle use more fuel?

Driving your vehicle “normally” you should actually see a pleasant improvement in fuel economy. However if you drive hard then you risk using more fuel. We receive many reports from customers claiming of up to 18% improvement.

Can I put the car back to original settings?

Yes you can. We would have to visit again and put back the original map.
