Nissan Interstar 2003-2011 2.5 DCi 100bhp remap figures
Thinking of remapping a Nissan Interstar 2.5 DCi 100bhp? The standard car makes 100bhp and 290Nm; with a Stage 2 remap from our Leicester workshop we expect around 165bhp and 375Nm, up to +65bhp and +85Nm.

Stage 2 remap figures
Stage 2 builds on Stage 1 with supporting hardware - typically a freer-flowing intake and exhaust or downpipe - and a remap written around those parts. Stage 2 is intended for off-road or competition use.

Who is the Stage 2 map for?
- Owners who have fitted, or plan to fit, supporting parts such as a freer-flowing intake and exhaust.
- Enthusiast, track and competition cars: Stage 2 is intended for off-road or competition use.
- Drivers who accept that a bigger gain means more of the car has to be checked and prepared first.
What Stage 2 needs
Stage 2 is written around supporting hardware. For an engine like this one that is typically a freer-flowing intake, an upgraded intercooler and a less restrictive exhaust. We confirm the exact parts for your car before any work starts.
- A diagnostic check and a read of your ECU come first.
- We look at the condition of the parts that will carry the extra power before we quote.
- Stage 2 is intended for off-road or competition use.
What this means for your Interstar
Diesel remaps work mainly on boost pressure, fuel delivery and torque limiters, which is why the Nm gain is usually the figure you feel in everyday driving, particularly when overtaking or towing.
Engine management is by a Bosch EDC16+C36 unit. Older engine management is simpler to work with, but age matters: worn sensors, leaks and tired components can hold back what a remap delivers, which is why we run a diagnostic check first.
We remap at our Belgrave Gate workshop in Leicester, or at your home or work within 30 miles, and every job starts with a diagnostic check.
Please note: these are expected figures, not guarantees. Real results vary with the condition of the vehicle, the ECU software version, fuel quality and the hardware fitted. Some options - including Stage 2 and anything that needs extra hardware - are for off-road or competition use only. We check every vehicle first and confirm what is achievable before any work starts.

Stage 2 questions
How much power does the Stage 2 map give the Nissan Interstar 2.5 DCi 100bhp?
We expect 165bhp and 375Nm against 100bhp and 290Nm as standard: up to +65bhp and +85Nm. These are expected figures, and we confirm what is achievable on your own car after a diagnostic check.
What does a Stage 2 remap need on the Nissan Interstar 2.5 DCi 100bhp?
Stage 2 assumes supporting hardware. For an engine like this that is typically a freer-flowing intake, an upgraded intercooler and a less restrictive exhaust. We confirm the exact parts for your car before any work starts.
Is Stage 2 for road use?
Stage 2 is intended for off-road or competition use. Tell us how the car is used and we will explain what we can and cannot do for it.
Do I need to tell my insurer about a remap?
Yes. A remap is a modification, so you should declare it to your insurer.
