Diesel · 4.0 litre · Maidstone, Kent

Mercedes ML 450 CDI remap306 to 350 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 ML 450 CDI from 306 to 350 bhp and from 700 to 810 Nm: 44 bhp and 110 Nm more, on standard hardware. Diesels gain most in torque, so the change shows as pull from low revs and less gear-changing under load, not just a higher peak figure. 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 ML 450 CDI remap questions

How much power does a Stage 1 remap add to a Mercedes ML 450 CDI?

44 bhp and 110 Nm. Standard is 306 bhp / 700 Nm; Stage 1 is 350 bhp / 810 Nm. That is a 14% power gain and 16% more torque.

How do I get a price for a Mercedes ML 450 CDI 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.

Will a remap affect the DPF or AdBlue on a Mercedes ML 450 CDI?

No. A Stage 1 remap keeps every emissions system as the factory fitted it. We do not remove or disable the DPF, EGR or AdBlue system as part of a remap.

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

A Stage 1 remap is around 2 hours, in a single visit. Add a dyno session and allow 4 to 5 hours. The original software is stored and can be restored on request.
