Petrol · 1.8 litre · Maidstone, KentSeat Leon 1.8 T remap210 to 240 bhp with Stage 1 software. The figures, the parts and the other engines in this car, on one page.
A Stage 1 remap takes the Seat Leon 1.8 T from 210 to 240 bhp and from 270 to 340 Nm: 30 bhp and 70 Nm more, on standard hardware. On a turbocharged petrol the gain comes from boost, fuelling and ignition timing recalibrated within the limits of the standard turbo and injectors. It is done in a visit at our Maidstone workshop and the original file is kept, so it can go back to standard.

How much power does a Stage 1 remap add to a Seat Leon 1.8 T?
30 bhp and 70 Nm. Standard is 210 bhp / 270 Nm; Stage 1 is 240 bhp / 340 Nm. That is a 14% power gain and 26% more torque.
How do I get a price for a Seat Leon 1.8 T remap?
Put the registration into the calculator and it prices Stage 1, 2 and 3 for this exact engine, or send the form on this page and we come back with a fixed price, usually the same day.
Is a Stage 1 remap safe for this engine?
Stage 1 stays inside what the standard turbo, injectors, clutch and cooling were built to take. The figures above are the calibration we run, not a maximum. The car is checked for stored faults before and after, and the original file is kept so it can go back on.
Does a remap affect the warranty on a Seat Leon 1.8 T?
A manufacturer can decline a warranty claim on a part they can show was affected by the remap. We tell you plainly what that means for your car and your warranty position before anything is done.
How long does it take, and can it be reversed?
A Stage 1 remap is done in a single visit, usually the same day. The original software is stored and can be restored on request.
