We at Celtic Tuning develop all of our own software in house using the very latest equipment.

All of our software is developed in our purpose built dyno cells running state of the art Dynocom 4WD rolling roads to ensure accuracy in terms of both power delivery and also to ensure fuelling, boost pressures and exhaust gas temperatures (where applicable) are all within tolerance.

We pride ourselves on our ability to achieve maximum power whilst maintaining optimum reliability.
