Typical Stage 1 gains are +25–35% power and +30–40% torque on turbocharged petrol and diesel engines. Enter your registration above for an instant car-specific quote.
Will a remap affect my insurance?+
A remap is a vehicle modification — we always recommend declaring it. We provide written before/after documentation on request for your insurer.
How long does a remap take?+
Most Stage 1 remaps are completed in 60–90 minutes including diagnostics, ECU read, write and a short road test. Mobile across West London.
