Today’s job took us right into the heart of rural Cornwall, out to Wendron near Helston—one of those locations where mobile tuning really comes into its own.
We don’t see many Alfa Romeos here in Cornwall, but the owner of this 2019 Alfa Romeo Stelvio was a lifelong Alfa enthusiast and had owned several over the years. When you meet owners like this, you know the car matters.
A Serious Performance Upgrade
This Stelvio was the 2.0 Turbo petrol model, producing an already respectable 197bhp from the factory. However, once we’d completed the remap, the final figures were nothing short of impressive:
- Final output: ~320bhp
- Massive increase in mid-range torque
- Sharper throttle response
- Effortless overtaking power
For a 2.0-litre petrol engine in a mid-size SUV, that level of performance is genuinely remarkable.
Bench ECU Remapping – The Right Tool for the Job
Unlike many vehicles we work on, this Stelvio cannot be accessed via the OBD port due to a factory security module. In these cases, the correct and safest approach is a bench remap.
That involves:
- Removing the ECU from the vehicle
- Connecting directly using specialist tooling
- Creating a full backup of the original software
- Writing a bespoke performance file
Fortunately, Alfa Romeo made the ECU easy to access, so aside from the Cornish rain, this was a straightforward and controlled job.

Why Specialist Tools & Experience Matter
Modern performance vehicles increasingly require bench tuning, secure boot access, or advanced tools. At Kernowsport, we invest heavily in:
- Manufacturer-safe tuning methods
- Multiple professional tuning tools
- Trusted calibration partners
- On-site mobile capability across Cornwall
That’s why we can confidently work on vehicles others simply turn away.
More Alfas, Please
This was one of those jobs that reminds us why we love what we do. Alfa Romeos still have that old-school pedigree, character, and driving feel—just backed up now with modern turbocharged performance.
If you own an Alfa Romeo in Cornwall or West Devon, we’d love to work on it.
