BMW X5 50i xDrive remap450 to 550 bhp with Stage 1 software. The figures, the parts and the other engines in this car, on one page.

A Stage 1 remap takes the BMW X5 50i xDrive from 450 to 550 bhp and from 650 to 820 Nm: 100 bhp and 170 Nm more, on standard hardware. On a turbocharged petrol the gain comes from boost, fuelling and ignition timing recalibrated within the limits of the standard turbo and injectors. It is done in a visit at our Maidstone workshop and the original file is kept, so it can go back to standard.

Is a Stage 1 remap safe for this engine?

Stage 1 stays inside what the standard turbo, injectors, clutch and cooling were built to take. The figures above are the calibration we run, not a maximum. The car is checked for stored faults before and after, and the original file is kept so it can go back on.

Does a remap affect the warranty on a BMW X5 50i xDrive?

A manufacturer can decline a warranty claim on a part they can show was affected by the remap. We tell you plainly what that means for your car and your warranty position before anything is done.

How long does it take, and can it be reversed?

A Stage 1 remap is done in a single visit, usually the same day. The original software is stored and can be restored on request.
