02 / The SGTM standard

CALIBRATION IS ONLY HALF THE STORY.

Great tuning starts before a file is written. The engine, control unit, software version and condition all matter to whether a calibration makes sense.

  • Review the actual vehicle and ECU platform
  • Diagnose relevant faults before changes
  • Discuss realistic outcomes and operating limits
  • Explain legal and insurance considerations
How we work
01
ENGINE FIRST.
SOFTWARE SECOND.

An engineering-led approach to performance.

03 / Four-stage approach

FROM ENQUIRY TO CALIBRATION.

01

Identify

Share your make, model, engine and ECU details.

02

Assess

Check compatibility, condition and project requirements.

03

Calibrate

Select appropriate tuning work where supported.

04

Review

Confirm next steps, limitations and service guidance.

04 / Performance, explained

SEE THE DIFFERENCE.
READ THE DATA.

A tuned calibration can change how power and torque are delivered. But the real story is always model-specific: different engines, software and hardware produce different results.

  • No universal horsepower promises
  • Calibration goals discussed before work
  • Genuine vehicle data when available

Conceptual illustration only — not measured dyno data, a real vehicle result, or a guaranteed performance gain.

06 / Why SGTM

BUILT FOR CONFIDENCE.

Not inflated dyno numbers or generic promises—clear, technical conversations around the vehicle in front of us.

Platform knowledge

The correct ECU and software version matter more than a badge.

Condition matters

Existing faults and mechanical limits are part of the discussion.

Realistic expectations

We explain what calibration may deliver, without universal gains.

Workshop-led

Stourbridge-based enquiries with mobile options where suitable.

Drivetrain thinking

Engine and transmission tuning assessed as one system.

Clear scope

A sensible work plan, costs and next steps before proceeding.

We will add authenticated customer reviews and measured remapping results only when the supporting records are provided.

07 / Independent, connected
