With a bespoke remap the Opel Astra 1.4 Turbo 140bhp gains +25 bhp and +65 Nm, rising from 140 bhp / 200 Nm to 165 bhp / 265 Nm (18% more power). We build each tuning file around the software number of your read on the Ac Delco E78, so nothing generic goes back into the car. Add DPF / EGR solutions 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). 140 → 165 bhp equals roughly 104 → 123 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.
