Our Stage 1 tuning file takes the Vauxhall Signum 2.8 Turbo 250bhp from 250 bhp and 340 Nm to 290 bhp and 400 Nm – that's +40 bhp (16%) and +60 Nm more. The remap file is written by a calibrator for your exact software on the Bosch ME9.6 and returned through the portal, normally within 5–15 minutes. Solutions such as DPF / EGR solutions 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). 250 → 290 bhp equals roughly 186 → 216 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.
