BMW M140i Remap
The BMW M140i is a cult performance car with a deeply capable B58 straight-six under the bonnet - and it's one of the finest remapping platforms in the hot hatch segment. Stage 1 takes the M140i from 340bhp to well over 400bhp with no hardware changes, making it a genuinely supercar-baiting sleeper. AutoCleanse provides M140i remapping from our Totnes workshop for enthusiasts across Devon and the South West.
