About Us

Workshop-based services plus mobile dealers across South Wales.

A little about us

We are specialist in vehicle tuning, coding, diagnostics, and vehicle security. We help drivers and businesses get more from their vehicles—whether that’s stronger performance and torque, better drivability, or added protection against theft.

Our approach to ECU & TCU remapping is simple: we aim for real-world gains without compromising reliability. We focus on responsible calibration, smooth power delivery, and keeping your vehicle safe to drive every day. For extra peace of mind, we provide a lifetime warranty covering software malfunctions, and we securely back up your original file so your vehicle can be returned to stock in the future if needed.

Beyond tuning, we also offer:

Coding & programming (unlocking factory functions and module programming)
Key programming & cutting
Alarms & immobilisers (including Thatcham-approved solutions such as CAN‑Phantom and Pandora)
Vehicle trackers (including Meta Track and SmarTrack, Thatcham accredited and insurer-approved options)
Dash cameras & reverse cameras
Van security (deadlocks, slam locks, OBD locks, statement locks and more)

If you want honest advice, quality work, and proper aftercare—get in touch and we’ll help you choose the right option for your vehicle.
