S63TU BMW V8 Twin-Turbo Tuning - M5/M6/X5M/X6M 2012+
BMW S63TU Performance ECU tuning software.
Gains: 110WHP/140WTQ at the wheels on our low reading Dyno Dynamics dynamometer. The engine will produce over 750HP at the crankshaft with our stage 2 tuning, and just over 700HP with stage 1 tuning on 100% factory hardware.
DMEs would have to be removed and shipped to our shop for flashing modified performance software to improve hp/tq significantly. Please label the DMEs with their original position, and reinstall back into same location after receiving them back.
Stage 1 and Stage 2 tuning available. 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.
