Stage 1 and Stage 2 remapping, gearbox tuning and rolling road sessions. We measure your car before we touch it, and again afterwards, and you leave with both printouts.
Send the reg and we come back with the figures for your exact engine and a fixed price. Usually the same day.
No obligation. We price it before anything is touched.
Standard against Stage 1 software, no hardware, measured the same day on the same dyno.




Our four-wheel rolling road, in house
Files written in this workshop since 2014
In and out the same day, most cars
Not happy? The original file goes back on
Put the registration in. If we have had one of these on our dyno you will see what it actually made. If we have not, you will see the range that kind of engine usually gives, and we will say so.
Measured on our own dyno, standard hardware, same day.
Stage 2 depends entirely on which parts are on the car, so we will not publish a figure for it. Bring it in and we will measure what it makes first.
Every published figure came off our own four-wheel dyno. Vehicle details come from the DVSA record. Contains public sector information licensed under the Open Government Licence v3.0.
Pick the badge and we will show the stages, the figures and the price for your exact engine.
There is no industry standard for the stages, so every tuner draws the line somewhere different. Here is where we draw ours.
| Stage 1Software only | Stage 2Software plus hardware | |
|---|---|---|
| What changes | Software only. Nothing is bolted on. | Software plus the parts that let it breathe — intercooler, intake, exhaust. |
| Typical gain | 15–30% on a turbo petrol. More on a diesel, because there is more torque to release. | Past what the standard hardware allows. |
| Time | One visit, usually the same day. | Two visits — parts fitted, then mapped and measured. |
| Reversible | Yes. Your original file is kept and goes back on. | Software yes. The parts stay on the car. |
| Price | £345 | From £1,850 with the full parts list |
| Best for | Almost everyone who asks us. | Owners keeping the car who want the next step. |

Plenty of places will sell you a map off a laptop in a car park. Every car here goes on the ramp for a health check before anybody opens the ECU, and on the dyno before and after so the numbers are measured rather than quoted.
Booked in for a Stage 1 and came away with the before and after printouts. No guesswork, no salesman — just the numbers.
They told me my intercooler was the limit before I spent anything on an exhaust. Saved me about six hundred quid.
Van does the same run on noticeably less fuel and pulls properly up the A38. Paid for itself inside four months.
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 — more poke, better mpg, or both. We come back with the figures for your exact engine and a fixed price, usually the same day.
