Diesel · 3.0 litre · Maidstone, KentMercedes E 300 CDI remap204 to 260 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 E 300 CDI from 204 to 260 bhp and from 500 to 600 Nm: 56 bhp and 100 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 E 300 CDI remap questions
How much power does a Stage 1 remap add to a Mercedes E 300 CDI?
56 bhp and 100 Nm. Standard is 204 bhp / 500 Nm; Stage 1 is 260 bhp / 600 Nm. That is a 27% power gain and 20% more torque.
How do I get a price for a Mercedes E 300 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 E 300 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 done in a single visit, usually the same day. The original software is stored and can be restored on request.
