Remapping & tuning for Carmarthen and Carmarthenshire drivers
Carmarthenshire is a different kind of motoring to the coastal towns — longer distances, faster A-roads, far more towing, and a much higher proportion of pickups, 4x4s and working vehicles. The tuning that suits it is different too. Peak power figures matter far less here than usable torque low in the rev range, where a loaded truck or a trailer actually lives.
Everything is verified on our MAHA 4-wheel rolling road — genuinely 4-wheel, which matters when the vehicle is permanent four-wheel drive.
Pickups, 4x4s and towing
A big share of our Carmarthenshire work is Hilux, Ranger, L200, Amarok and Defender, and the brief is nearly always the same: make it pull properly with a livestock trailer or a horsebox on the back, without cooking the drivetrain.
That means a torque-led map built around sustained load rather than a peaky headline number, and a frank conversation about clutch condition before we start — a tired clutch on a towing vehicle will show itself the moment torque goes up. Our guide on remaps and clutch slip explains what to look for.
Agricultural and plant machinery
We also work on tractors, telehandlers, generators and plant — equipment where fuel burn over a season is a real cost, and where manufacturers often ship several power outputs of the same engine. Our plant and machinery tuning guide covers what is realistic. If you have something unusual, ask — we would rather tell you honestly that we cannot help than guess.
Getting to us from Carmarthen
Our workshop is at Unit 1F, Cwmgors Industrial Estate, Park Howard Rd, Gwaun-Cae-Gurwen, Ammanford, SA18 1PA — about 24 miles from Carmarthen, so allow around 35 to 40 minutes.
Head east on the A48 to the Cross Hands roundabout, then take the A476 south-east through Ammanford, and follow the signs for Gwaun-Cae-Gurwen and Cwmgors. It is an easy run, and largely dual carriageway or open A-road for the first half.
