Our Stage 1 tuning file takes the Subaru WRX 2.0T 286bhp from 286 bhp and 350 Nm to 300 bhp and 400 Nm – that's +14 bhp (5%) and +50 Nm more. The remap file is written by a calibrator for your exact software on the Hitachi DEF003 and returned through the portal, normally within 5–15 minutes. Solutions such as DTC Removal can go into the same file.
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). 286 → 300 bhp equals roughly 213 → 224 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.
