All of our tuning files are custom written in house to suit driver and car always taking into account car engine condition and mileage. Some tuners or consumers still refer to ecu remapping as chip tuning and although its the same end result, most newer cars can not be "chipped" anymore.

Do I need stage 1, 2 or 3?

Stage 1 tune is a software re-calibration only.
Stage 2 tune is software re-calibrated to work with light engine modifications e.g Air Filter, exhaust, intercooler.
Stage 3 tune is software re-calibrated on the dyno for heavy engine modifications e.g Cold air intake, exhaust, intercooler, turbo upgrade and more.

Why is my vehicle not already optimised for peak performance?

Manufactures sell vehicles with a standard set of map files on the ECU so they can be shipped all around the world. Vehicles are shipped around the world meaning they have to deal with different climates and a magnitude of fuel types and quality, this is why the manufactures set a standard map that will simply work anywhere. Power and fuel economy is also limited on these maps because of market placement and sales tactics. For example; BMW needed to limit the power of the 335D just so its pace isn’t that of an M3. Performance engine tuning is essential for those drivers who feel their vehicle is not living up to its full potential. By increasing the power of your vehicle you are providing yourself with a more pleasurable car to drive that puts that smile back on your face. Whether the gain is 5 BHP on your 1.4 Ford Focus or 55 BHP on your BMW 335d, when you choose a JF Automotive ECU performance map, you will wonder why you didn’t come to us sooner! Get My Price
