Our unit in LatchingdonWho we are
Thirty five years on the tools
P&J Tuning is Paul Nash and the team at Mayfair Industrial Estate, Latchingdon. We have been at this since 1990: a full garage first, doing servicing, repairs and diagnostics on cars, vans and commercial vehicles.
The remapping sits alongside that rather than instead of it, which is the difference. We see the whole vehicle, not just its software, and the brake testing facility on site means a commercial can be sorted and signed off in one place.
- A garage, not just a laptopServicing, repairs and diagnostics every day. The mapping is one more thing we do, not the only thing.
- HGV as well as carsThirty five years of commercial work, and a brake testing facility on site.
- The original is keptYour factory file is saved before anything is written, so it can go back to standard.
- Prices up frontWhat we charge is on the site. No ringing round for a number.
- You get told the truthIf a map is not what the vehicle needs, we will say so.

What we do
Remapping, diagnostics and the checks in between
Stage 1 remapping
The standard tune for a standard vehicle. More power, sharper throttle, no hardware changes.
Stage 2 and custom files
For vehicles with an upgraded exhaust, intake, intercooler or hybrid turbo.
HGV and commercial
Trucks, tractor units and commercial fleets, alongside the car work.
01
Stages
The main calibrations. Each one is written for your exact engine and gearbox code, never picked off a shelf.
- Stage 1Standard hardware. Fuelling, boost, timing and torque limiters adjusted inside factory tolerances.Road
- Stage 1+The most we will sensibly take a standard car, with the factory emissions systems left working.Road
- Stage 2For cars already running an upgraded exhaust, intake, intercooler or downpipe.Road
- Stage 3Hybrid or upgraded turbo with uprated fuelling and the supporting hardware to match.Ask
- Stage 4Built around a car put together for drag and competition work.Track
- Sport mode onlyFactory power in normal mode, the tune applied only in sport. Useful on a shared or company car.Road
- Economy calibrationAimed at mpg rather than headline power. Low end torque lifted so the engine works less hard at a cruise.Road
Vehicle stats
See what your car should make
Put your registration in and the lookup pulls the manufacturer figures for your exact engine, then shows the power and torque we would expect after mapping. It takes a few seconds and it does not commit you to anything.
- Reads the exact engine and gearbox from the plate
- Standard figures next to the mapped estimate
- Send the result straight to us for a price
Before and afterWhat to expect
Honest numbers, not headline ones
Every engine responds differently, so we would rather show you one real result than quote a percentage that suits us. This is a common 2.0 diesel with nothing changed but the software.
Example result2.0 TDI 150, standard hardware
| Measure | Standard | After mapping | Change |
|---|---|---|---|
| Power | 148 bhp | 148 | +37 bhp |
| Torque | 236 lb/ft | 236 | +59 lb/ft |
| 0 to 60 | 8.9 sec | 8.9 | 1.1 sec quicker |
Example figures from one car. Yours will differ with fuel, condition and mileage. Replace this block with your own logged results.

Cars to HGV
One garage for the whole fleet
Most places that map cars will not touch a truck, and most truck places do not map. We do both, from the same unit, with a brake testing facility on site. For an operator that means one phone call instead of three.

- Servicing and repairs, not just software
- Brake testing on site, no second trip
How it works
Three steps, no surprises
Check, then map
The car is looked over for faults first. Only then does the file go on, and it gets road tested or logged afterwards.
Drive it, then tell us
If anything does not feel right in the first few weeks, bring it back. Revisions on your file are included.
