You wont find many people that have had a service from us, it isnt our everyday work as we spend 90% of our time on the dyno. A lot of our customers that have our software installed come back for servicing, brakes etc... As they like to avoid main dealers.
We use all o.e parts as part of our services, tbh theres nothing too technical needed for general servicing just need to be thorough and give everything a good check over.
