Petrol · 3.0 litre · Maidstone, KentBMW Z4 35is remap340 to 370 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 Z4 35is from 340 to 370 bhp and from 450 to 520 Nm: 30 bhp and 70 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 Z4 35is remap questions
How much power does a Stage 1 remap add to a BMW Z4 35is?
30 bhp and 70 Nm. Standard is 340 bhp / 450 Nm; Stage 1 is 370 bhp / 520 Nm. That is a 9% power gain and 16% more torque.
How do I get a price for a BMW Z4 35is 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 Z4 35is?
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.
