PSI Tuning's service work can be tailored to suit the customer's requirements. Depending on the needs and uses of their vehicle we start with a basic package of a 10k service consisting of a part vehicle inspection, oil change and filter elements inspected.

Our 20k service is the equivalent to the dealer's 40k service and consists of a full vehicle inspection, replacement of filter elements, replacement of engine fluids and replacement of spark plugs (petrol engines only).

The customer is given full documentation and a report. A longlife service is also available. Full prices are at the bottom of this page.


As well as our growing reputation when it comes to service & performance work. PSI Tuning also has an excellent knowledge when it comes to fault finding.

We would like to think that with the amount of experience we have gained over the years, we have encountered most faults at least once, and if we haven’t, we’ll have enough combined knowledge to know where to start from.

We have a variety of hardware and software such as VAG-Com to look into electrical issues and can clear fault codes, reset service lights and other advanced functions and coding.

More Power ! More MPG!

For customers who desire to improve performance it is possible to obtain an increase in power up to 5-8% on atmospheric engines and up to the 30% on boosted ones. Similar improvements are gained in the torque curve as well. Even our performance remaps will give an economy boost under the same driving conditions. Gains from 5mpg are generally seen across the board.

We can cover almost all models from 1998 onwards and our staff have been remapping cars since 1996 so we have a wealth of experience along with the latest technolgy of remapping systems and rolling road in our premises.

We charge just £250 inc vat to remap your vehicle (excluding engines over 4.0l)
