Diesel · 4.4 litre · Maidstone, KentLand Rover Range Rover 4.4 SDV8 remap339 to 390 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 Land Rover Range Rover 4.4 SDV8 from 339 to 390 bhp and from 700 to 820 Nm: 51 bhp and 120 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
Land Rover Range Rover 4.4 SDV8 remap questions
How much power does a Stage 1 remap add to a Land Rover Range Rover 4.4 SDV8?
51 bhp and 120 Nm. Standard is 339 bhp / 700 Nm; Stage 1 is 390 bhp / 820 Nm. That is a 15% power gain and 17% more torque.
How do I get a price for a Land Rover Range Rover 4.4 SDV8 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 Land Rover Range Rover 4.4 SDV8?
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.
