Forty minutes down the M1. Chesterfield is the furthest most people travel to us, and almost everyone who makes that journey is coming for dyno time rather than software alone.
Send the reg and we come back with the figures for your exact engine and a fixed price.
No obligation. We price it before anything is touched.
We are honest about this: if all you want is a file written, there is somebody nearer to you and you should use them. Software is software, and the drive is not worth it.
What is worth it is the measurement. Four-wheel dynos are not common, and the ones that exist are not always in workshops that will show you the graph and explain it. That is the reason people come from Chesterfield.



A recurring job from your direction: somebody has bought a car advertised as modified and wants to know what it actually makes. Often the answer is less than the advert said, and occasionally it is nothing at all.
A rolling road session on its own is £150 and it settles the question in an hour. It is the cheapest piece of due diligence available on a modified car.
Two runs on the same dyno on the same afternoon, printed, with somebody talking you through what the lines mean. You leave knowing what your car made before and after rather than what somebody claimed.
If that is not what you want, we would genuinely rather you saved the fuel and went local. It is not false modesty — an unhappy customer who drove forty minutes is worse for us than no customer.
Chesterfield town, Brampton, Whittington. The bulk of what comes down the M1.
Clay Cross, Staveley, Barlborough. Mixed commercial and private.
Bolsover and the villages. Longer runs, healthier engines.
Dronfield. Closer to Sheffield, but they still come to us for the measurement.
Both work. Forty minutes and almost all of it motorway.
The slower alternative, and prettier if you are not in a rush.
For software alone, no — go local. For measured before-and-after figures, yes, and that is why people make the trip.
About forty minutes down the M1 to J28 or J29. Almost all motorway, so it is an easy run.
Book a rolling road session on its own. £150, about an hour, and you will know exactly what it makes rather than what the advert claimed.
Yes. Plenty of people do, and there is no pressure to have work done off the back of it.
Yes, before you pay. A dyno graph is easy to misread and we would rather you understood it than were impressed by it.
No. The price is the price wherever you have come from.
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.
Send the registration and what you want from the car. We come back with the figures for your exact engine and a fixed price, usually the same day.
