Hybrid · 3.5 litre · Maidstone, KentMercedes S 400 Hybrid remap333 to 380 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 Mercedes S 400 Hybrid from 333 to 380 bhp and from 370 to 450 Nm: 47 bhp and 80 Nm more, on standard hardware. On a plug-in hybrid the remap works on the combustion engine only; the electric motor and battery are untouched, so EV range and charging are unchanged. It is done in a visit at our Maidstone workshop and the original file is kept, so it can go back to standard.

Questions
Mercedes S 400 Hybrid remap questions
How much power does a Stage 1 remap add to a Mercedes S 400 Hybrid?
47 bhp and 80 Nm. Standard is 333 bhp / 370 Nm; Stage 1 is 380 bhp / 450 Nm. That is a 14% power gain and 22% more torque.
How do I get a price for a Mercedes S 400 Hybrid 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 remapping a Mercedes S 400 Hybrid affect the battery or electric range?
No. The remap changes the petrol engine calibration only. The high-voltage battery, motor and charging are not touched, and EV range is unchanged.
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.
