BMW N63 with MSD85 Performance ECU tuning software.
Will work in the following BMW models:
2008– 2013 E71 X6 xDrive50i
2009– 2012 F01/F02 750i/750Li sDrive/xDrive
2010– 2012 F07 550i GT sDrive/xDrive
2011– 2013 F10/F11 550i sDrive/xDrive
2011– 2013 E70 X5 xDrive50i
2012– 2012 F12/F13 650i sDrive/xDrive
Gains: 77WHP/71WTQ at the wheels on our low reading Dyno Dynamics dynamometer. The engine will produce around 540HP at the crankshaft with our stage 1 tuning on all original hardware.
DME would have to be removed and shipped to our shop for flashing modified performance software to improve HP/TQ significantly.
Top speed limiter (VMAX) is disabled.
Performance tuning modifies torque limiter maps, boost levels, fuel maps, ignition timing advance maps and more. All to help safely increase HP/TQ, while keeping good drive-ability and factory fail-safes/limp protection in place.
