With a bespoke remap the Audi A4 40 TFSI G-Tron (2.0T) 170bhp gains +30 bhp and +50 Nm, rising from 170 bhp / 270 Nm to 200 bhp / 320 Nm (18% more power). We build each tuning file around the software number of your read on the Bosch MG1CS001 / Bosch MG1CS111, so nothing generic goes back into the car. Add DTC Removal 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). 170 → 200 bhp equals roughly 127 → 149 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.
