About us
Engine management specialists.
MAS Performance has over 13 years' experience in the motor trade, specialising in engine management systems. What started with Fiats grew into V.A.G and Vauxhall and, today, custom tuning for cars, vans, trucks, tractors and plant across the UK.
How we work
Our own software, our own dyno.
Every file we write is developed in-house and tailored to the individual vehicle — we never load generic third-party files. Cars are tuned and proven on our 2WD rolling road with full data acquisition, and we run commercial R&D on an independent truck dyno.
- ✓ In-house, tailored software — never generic
- ✓ Your original file is always kept
- ✓ Full before & after diagnostic and data logging
- ✓ Rolling road & independent truck dyno
- ✓ All work guaranteed
