Why the check matters
A remap asks more of the engine — more boost, more torque, more heat. If something is already weak, tuning can turn a small problem into an expensive one. A health check catches those problems first, which is why we include one with every single job.
What we actually check
A proper pre-remap inspection goes well beyond reading fault codes:
- Full system diagnostic scan across all modules
- Live data — boost pressure, fuel rail pressure, sensor readings
- Stored and pending fault codes, properly interpreted
- Visible checks — leaks, perished hoses, general engine condition
- Service history and maintenance questions — oil, plugs, filters
What happens if we find something
We tell you straight. Sometimes it's a cheap fix — a coil pack or a split hose — and the remap can go ahead after. Sometimes it's a sign the car needs work first. Either way, you'd rather know before the map than after.
How you can prepare
Fresh oil and a recent service help any tune. If your car is due a service, has a warning light on, or hasn't been looked at in a while, mention it when you book — we'd rather plan around it than discover it on your driveway.
