BMW S63 with MSD85 Performance ECU tuning software.
Will work in the following BMW models:
Gains: 62WHP/75WTQ at the wheels on our Mainline ProHub 5000 dynamometer.
DME would have to be removed and shipped to our shop for flashing modified performance software to improve HP/TQ significantly. We will make a full back up copy of the DME for safe keeping, and can always recover back to original or clone it onto another DME.
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.
