DKR Tuning has changed one of ten things on the Porsche 911 Turbo to produce a scintillating 540 bhp and 775Nm out of the same 3.6-litre boxer engine.

Those owners of the Porsche 911 Turbo who aren’t entirely satisfied that their car really is the powerhouse Porsche claims it is, can turn to German tuner DKR for a €5,529 power upgrade. DKR Tuning optimises the ECU software and fits a new sports exhaust system to garner a forceful 540 bhp/ 402kW and 775Nm from the car’s twin-turbo 3.6-litre boxer engine.

After having upgraded the engine one might feel a little more adventurous and go kit mad. For that DKR provides 19-inch Cargraphic RS alloy wheels on 235/35 tyres in front and 305/30 at the rear. A functional front lip spoiler and larger rear wing gives that macho appearance that accompanies all this power. It’s a 911 so handling needs no introduction, even at full 540 horses on the throttle.
