Porsche 911 GT3 RS 3.8i 435bhp tuning file

With a bespoke remap the Porsche 911 GT3 RS 3.8i 435bhp gains +20 bhp and +20 Nm, rising from 435 bhp / 430 Nm to 455 bhp / 450 Nm (5% more power). We build each tuning file around the software number of your read on the Siemens/Continental SDI9, 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). 435 → 455 bhp equals roughly 324 → 339 kW.
