With a bespoke remap the Seat Altea / XL 1.2 TSI 105bhp gains +45 bhp and +50 Nm, rising from 105 bhp / 175 Nm to 150 bhp / 225 Nm (43% more power). We build each tuning file around the software number of your read on the Siemens/Continental Simos 10, so nothing generic goes back into the car. Add DECAT, DTC Removal, FLAPS, Pop & Bang Crackle map to the same file if needed.
Who is this remap for?
On a turbo petrol, a remap sharpens throttle response and pulls harder through the mid-range. For the best result we recommend running it on super unleaded (97–99 RON). 105 → 150 bhp equals roughly 78 → 112 kW.
Figures are guide values from our rolling road and comparable vehicles. Results depend on the vehicle's condition, hardware and fuel quality. Remapping in the UK: let your insurer know about the modification. DPF, EGR and AdBlue solutions are supplied for off-road and motorsport use only and are not legal for use on UK roads.
