BMW S63TU Performance ECU tuning software.
Gains: 149WHP/146WTQ at the wheels on our Mainline ProHub5000 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.
We offer this tuning via OBD2 flash option at this time, we will mail out a cable that you will keep.
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.
