N63 BMW V8 Twin-Turbo Tuning - F10 550i, F01 750i, X5/X6 50i, F12 650i
BMW N63 with MSD85 Performance ECU tuning software.
Will work in the following BMW models:
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.
Stage 1 tuning available at this time, stage 2 will be released soon. Stage 1 tuning is for all stock hardware. Stage 2 tuning is for off-road use only with catless downpipes. Cat codes are removed with stage 2 software to prevent a CEL.
Top speed limiter (VMAX) is disabled with both, Stage 1 and Stage 2 tuning options.
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.
Please print out this form and mail it in with your DME. DME will not be flashed until the form is filled out and sent to us. Thank you.
