Petrol · 3.0 litre · Maidstone, KentBMW M4 CS remap460 to 510 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 M4 CS from 460 to 510 bhp and from 600 to 720 Nm: 50 bhp and 120 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.

Questions
BMW M4 CS remap questions
How much power does a Stage 1 remap add to a BMW M4 CS?
50 bhp and 120 Nm. Standard is 460 bhp / 600 Nm; Stage 1 is 510 bhp / 720 Nm. That is a 11% power gain and 20% more torque.
How do I get a price for a BMW M4 CS remap?
Put the registration into the calculator and it prices Stage 1, 2 and 3 for this exact engine, or send the form on this page and we come back with a fixed price, usually the same day.
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 M4 CS?
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.
