Petrol-specific considerations
Petrol calibrations are sensitive to ignition timing and knock control. Fuel grade matters: some calibrations are written for a particular octane rating, so we will discuss which fuel the car will use. Spark plugs, coil packs and intake condition also affect results, and a misfire or knock-related fault code needs attention before tuning.
Many newer petrol engines have gasoline particulate filters (GPF/OPF). Like a diesel DPF, these stay in place and working with any road-going calibration.
Turbocharged versus naturally aspirated
Most of the change available from a petrol remap comes from boost on turbocharged engines. On naturally aspirated engines the change from software alone is usually modest, and throttle response or rev-limit adjustments may be all that is sensible. We would rather explain that than sell a remap that is not worth it to you.
Hot hatches and performance cars may already be calibrated closer to their limits, and their condition — especially clutch, cooling and turbo health — needs careful checking.
How we approach a petrol remap
We start with suitability rather than a sales pitch. Before any calibration is written to a control unit we want to know the vehicle is healthy: existing fault codes, boost or fuelling problems, a slipping clutch, a worn gearbox or a blocked DPF all need to be dealt with first, because tuning is not a substitute for repair and can make an existing weakness more obvious.
Where the vehicle is supported we explain what the proposed calibration is intended to change, what checks are needed and what the agreed scope of work includes. We do not publish universal power, torque or fuel-economy figures, because results depend on the individual vehicle, its condition, its software and how it is driven. If a remap is not the right answer for your vehicle, we will tell you.
What to send us before booking a petrol remap
The quickest way to get useful advice is to send the registration and a short description by WhatsApp or through the quote form. Support and suitability vary by engine, gearbox, control unit and software version, so a registration lets us check the right information instead of guessing. Any estimate given remotely is provisional until the vehicle has been seen and the required checks are complete.
- 01Vehicle registration and approximate mileage
- 02Make, model and engine size, if known
- 03Any warning lights, messages, symptoms or fault codes
- 04Existing remaps, tuning boxes or hardware modifications
- 05How the vehicle is used — commuting, towing, short trips or heavy loads
- 06Whether the vehicle is currently in limp mode or will not start
Visiting the workshop for a petrol remap
All work is carried out at our single workshop at Unit 2, Lancaster Works, Kingsbridge Road, Manchester M9 5SP. We do not run a mobile remapping service and we have no other branches, so every a petrol remap enquiry is booked into the same Manchester workshop. Visits are by arrangement: please call or WhatsApp before travelling so we can confirm the vehicle, the time and what the visit will involve.
Access is through the black gate. Call when you arrive so we can let you in, then keep left towards the rear of the site. We are open Monday to Friday 8am–6pm and Saturday 8am–1pm, and closed on Sunday. If the vehicle is in limp mode, showing a serious warning or will not start, tell us before setting off so we can talk about whether it is sensible to drive it or whether transport should be arranged.
