BMW 5 serie 528i 245bhp tuning file

With a bespoke remap the BMW 5 serie 528i 245bhp gains +35 bhp and +80 Nm, rising from 245 bhp / 350 Nm to 280 bhp / 430 Nm (14% more power). We build each tuning file around the software number of your read on the Bosch MEVD17.2.9 / Bosch MEVD17.2.4 / Siemens/Continental MSD87 / Siemens/Continental MSV90, 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?

Naturally aspirated petrol engines gain less than turbo engines, but a remap still improves throttle response and smooths out flat spots in the power delivery. 245 → 280 bhp equals roughly 183 → 209 kW.
