Power & Torque Gains
Power & Torque Gains
Enjoy increased power from your vehicle throughout the entire rev range.
We design our maps to make power come in sooner, make great torque gains and hold them for as long as possible. Whilst we do make great peak power increases, for most vehicles this is not the primary focus of our tuning. We aim to get the best power possible across the whole rev range to make your vehicle perform best in real world driving conditions.
Our units considerably reduce turbo lag and will make your vehicle easier and more fun to drive.
Your vehicle should make very similar power and torque gains to those quoted, though small variances from vehicle to vehicle, and from dyno to dyno are to be expected.
"Before" figures quoted are based upon manufacturer's stated power output.
- 5 User Selectable Power Curves to suit your requirements,ranging from milder gains to all out performance.
- Reprogrammable for future vehicles. No need to purchase multiple remaps or tuning modules, keep your Bluespark Petrol Turbo Tuning Module and send it in for reprogramming should you change vehicle in the future.
- Weatherproof Aluminium Casing to keep dust and water out in an under bonnet environment
For Diesel vehicles we expect to see improvements in fuel economy of around 10%. This means if you currently get 50 MPG you might expect to see somewhere around 55 MPG. This is very dependent upon your driving style. If you use the extra power and drive faster naturally the economy benefits will be lessened.
