One workshop, where the dyno is

EC Performance is workshop-based. Every remap, diagnosis, key and security install is done at our unit on the Cwmgors Industrial Estate in Gwaun-Cae-Gurwen, because that is where the MAHA 4-wheel rolling road is — and we would rather measure a result than guess it. These are the towns most of our customers drive in from, with typical distances and drive times.
