Stage 1 ECU Remap Results We recently carried out a Stage 1 ECU remap on a 3.0L diesel Range Rover, delivering strong, usable gains while preserving the smooth, refined character these vehicles are known for. Performance figures: Stock: 306 hp / 700 Nm Stage 1: 330 hp / 750 Nm Increase: +24 hp / +50 Nm This calibration is focused on **real-world performance and drivability**, not inflated headline numbers. How It Transforms the Drive From factory, these vehicles are intentionally tuned to feel calm and effortless. While that suits motorway cruising, it can sometimes leave the car feeling slightly hesitant at lower speeds or when quick response is needed. A Stage 1 remap refines this behaviour without taking away from the comfort: More immediate throttle response when pulling away Smoother, more predictable low-speed control Stronger, more usable mid-range torque for overtaking A more natural connection between throttle input and vehicle response The result is a vehicle that still feels relaxed when cruising, but responds exactly when you ask it to . Everyday Benefits You’ll Notice Rather than changing the character of the vehicle, the aim is to enhance it: Easier, more confident pull-away at junctions and roundabouts Less need to push the throttle for everyday acceleration Smoother power delivery through the gears Effortless cruising with improved efficiency potential It’s a subtle but meaningful difference — the kind you notice within minutes of driving. Optional Add-Ons We can tailor the setup to your requirements on the day: Speed limiter removal Dealer-Level Diagnostics Included Every vehicle undergoes a full dealer-level diagnostic health check before and after tuning to ensure: No underlying faults Safe calibration conditions Verified performance improvements Fully Mobile ECU Remapping – Somerset & South Wales We provide a fully mobile ECU remapping service across Somerset and parts of South Wales , meaning we come directly to your vehicle: Home or workplace No travel charges within our core service area Minimal disruption to your day Areas commonly covered include: Weston-super-Mare Bristol Chepstow Newport Cardiff Instant BHP Checker Want to see what your vehicle can achieve?
