Services

Mobile tuning, diagnostics and emissions solutions across the Midlands. Operated by Precision Remaps UK.

Stage 1 ECU Remap

A safe, custom calibration designed to improve performance and drivability with no hardware changes. Expect sharper throttle response, stronger mid-range torque and smoother power delivery.

  • Custom file per vehicle (no generic maps)
  • Improved torque and response
  • Ideal for daily driving

Stage 1+ (With Supporting Mods)

Consultation required

For vehicles with mild supporting modifications (e.g. intake/exhaust on suitable setups), we can tailor the calibration to match hardware.

  • Map aligned to your setup
  • Safer than “off-the-shelf” files
  • Ideal stepping stone to bigger builds

Stage 2 ECU Remap

Consultation required

Designed for vehicles with supporting hardware upgrades such as upgraded intake, exhaust, intercooler or sports catalyst. Calibrated specifically to match the fitted parts.

  • Requires supporting modifications
  • Higher power and torque than Stage 1
  • Custom calibration to suit your setup

Stage 3 ECU Remap / Big Turbo Builds

Consultation required

Full custom tuning for heavily modified or big-turbo vehicles. This is a bespoke service tailored to hardware, fuel system and drivetrain limits.

  • Big turbo & injector upgrades supported
  • Fueling, boost & torque modelling tailored
  • Pre-book consultation before tuning

Eco Remap

Optimised torque and efficiency for drivers who want better MPG and smoother cruising. Best results come from sensible driving and regular maintenance.

  • Lower throttle demand for the same speed
  • Great for motorway & long-distance use
  • Diesels often see the biggest gains

DPF Solutions (Diagnostics-Led)

If your DPF is causing limp mode, constant regenerations or fault codes, we start with proper diagnostics to identify the real cause — not guesswork.

  • Differential pressure & soot/load checks
  • Regeneration support where appropriate
  • Advice based on your usage + faults

EGR Solutions (Diagnostics-Led)

EGR issues can cause hesitation, rough idle, smoke, or recurring engine lights. We assess the vehicle and advise the best route based on symptoms and fault codes.

  • Fault-code guided assessment
  • Improved drivability when EGR is faulty
  • Clear explanation before any work

AdBlue / SCR Solutions (Diagnostics-Led)

AdBlue faults can lead to countdown starts, no-start situations and expensive parts swaps. We diagnose the system first and advise the most sensible fix.

  • NOx/pressure/pump & fault checks
  • Support for common SCR issues
  • Mobile service — no recovery needed

Advanced Diagnostics

Fast, accurate fault finding for engine, emissions and drivability issues. Perfect before spending money on parts.

  • Live data review + code interpretation
  • Root-cause approach
  • Clear next steps & options

Gearbox Software (Where Suitable)

For certain vehicles, gearbox tuning can improve shift strategy and torque handling. Recommended mainly on higher-torque builds or DSG-type transmissions.

  • Smoother shifts (where supported)
  • Better torque control
  • Vehicle-dependent availability
