Whifbitz 694BHP BMW M4 

2015 BMW M4 tuned and modified by Garage Whifbitz.

Our car is currently running 694bhp & 674 lb/ft torque, we’ve been busy developing & testing different ways of mapping the BMW S55 engine mainly because of the huge amount of torque that these engines produce and the way this is transmitted to the ground. Being rear wheel drive, tuning the BMW M4/M3 can actually make the car slower as it just lights the rear tyres up! So we are now offering a much more progressive tuning option as shown below on the dyno graph. The method brings the torque in more gradually giving the tyres a chance to grip! We can offer both methods if required though, if you want all the torque in low down similar to the way they are mapped from the factory.

Our car is currently running the following modifications:

  • Custom Ecutek Racerom mapping here at Garage Whifbitz on our Dynojet rolling road. Switchable maps on the steering wheel, low boost and high boost with adjustable torque levels via the steering wheel
  • Whifbitz 3″ downpipes
  • VRSF single midpipe
  • K&N drop in air filters
  • NGK 97506 iridium spark plugs
  • FTP Motorsport Aluminium charge pipes
  • BMS oil catch tank
  • 20″ Z Performance Wheels with 265/30 front and 305/30 rear tyres
  • Eibach Pro Kit lowering springs
  • Carbon engine cover
  • Carbon side skirts, rear diffuser, rear spoiler & front spoiler
  • Black M4 rear badge
  • Black grilles
  • Black side garnish
