Harrow and Our Slough Workshop
Harrow is in North West London; this page covers town enquiries, not a local STX branch.
If your car needs additional ECU access, gearbox software or performance hardware installation, we can discuss bringing it to our Slough workshop. For compatible vehicles, see mobile remapping.
Remapping Services in Harrow
Choose a service around your vehicle and priorities, not your postcode alone. A standard supported setup may suit Stage 1; economy tuning focuses on usable torque without guaranteed fuel savings. Stage 2 needs a defined hardware specification, while gearbox support depends on the transmission version.
Workshop or Mobile in Harrow?
There is no STX branch in Harrow; our workshop is in Slough. Harrow is within our normal mobile area, so send your registration and the exact postcode and we will confirm whether your vehicle suits a mobile appointment or needs the Slough workshop. Supported diagnostic-port programming may suit a mobile visit; certain unlocks, ECU removal and hardware fitting need workshop arrangements. We confirm the postcode, vehicle and scope before booking.
Check Your Vehicle
Compare the listed engine variants and available estimates. Missing figures are not evidence of compatibility, and estimated output is not a guaranteed result.
