What we do

Eight services,
one set of dyno

Most people who ring want the same thing and do not know it is called a Stage 1. The rest of this list exists for when it is not.

No obligation. We price it before anything is touched.

Tell us the symptom, not the service

Nobody arrives knowing whether they want a Stage 1, a gearbox tune or a diagnostic, and there is no reason you should. Describe what the car is doing, or what you wish it did, and we will tell you which of these it is.

Including when the answer is that you do not need us. A car that is down on power because something has failed is a repair, not a tuning job, and we would rather book the diagnostic than sell you a map.

Questions

Choosing a service

I just want it quicker. Which one is that?

A Stage 1 remap. It is software only, it needs no parts, and for the overwhelming majority of road cars it is the entire job.

What is the rolling road on its own for?

Finding out what a car actually makes before you spend anything. Worth it if you have bought a car with claimed modifications, or if something feels down on power and nobody can say why.

Do I need gearbox tuning as well?

Only on an automatic where the box is limiting the engine — usually a DSG, S tronic or ZF with a torque limiter below what the engine can now make. On a manual, no.

My van is for work, not speed.

Then you want the economy side of the same job: more torque low down so the engine works less at motorway speed. On a diesel doing big miles it usually pays for itself.

Something is wrong with it rather than slow.

Book the diagnostic first. It is £95, it takes an hour, and it tells you whether you have a tuning job or a repair job before you spend money on the wrong one.

How do I know which I need?

Send the registration and a sentence about what is bothering you. We will tell you which service it is, including when the answer is none of them.

Where we work

Where we work

Software-only jobs we do at your address — driveway, office car park or yard. Anything that needs measuring comes to the unit, because a rolling road does not travel.

Tell us the job and we will say which one it is before you book.

Ready when you are

Describe the car.
We will name the job.

Send the registration and what is bothering you. We come back with the service it needs, the figures and a fixed price, usually the same day.
