DMS BMW 535d - A Very Serious Power Tool

"The 535d Is Already Stonkingly Fast, But A Simple Tweak Can Make It Ludicrously So"

"By re-profiling the 535d's engine management computer, torque is ramped up from 413lb ft to a claimed to 478lb ft, with power up from 272bhp to a claimed 321bhp.
Enormous torque, effortless pace.
This car is astonishingly, ludicrously fast at all speeds, but especially above 100mph."
