TUNING F10 CUSTOM TUNE
F10 ·S63TU ENGINE ·BM3 CUSTOM CALIBRATION

BMW F10 M5 (S63TU)

Logged, verified, revised. Documented in writing. Yours to keep.

A custom bootmod3 calibration for the F10 M5 (S63TU) — built from datalogs on your car, not a map off a shelf. This is the M-division super-sedan, and the S63TU is a genuine performance engine — so we calibrate it as one, reconciling timing, knock, fuel trims, and load against your own logs until the math and the data agree. Owners here are usually serious about street and track, and the tune is built to that standard.

A four-door that runs hard deserves a calibration that's documented and repeatable, not a one-size map — which is why each Stage is logged and revised on your specific car.

How we approach it

Math first, datalogs second, marketing claims a distant last. We don't publish dyno numbers we can't reproduce; we tune to what your specific car does on the fuel you actually buy.

How we calibrate this platform.

Methodology notes for this chassis publish with its first documented build. The process is the same on every car we touch: datalogs in, ignition and fuel changes out, a revision log in writing.
ANSWERED

Before you tune.

How long until I have a working tune?

4-5 business days from datalog receipt for Stage 1; 7-10 days for Stage 2.

Do I need supporting hardware for Stage 2?

Chargepipe and a fuel system check are recommended. E30 flex requires a flex-fuel kit on chassis that don't ship one factory.

Can I revert to stock for warranty service?

Yes. BM3 supports non-destructive stock revert. Most customers revert before dealer appointments and re-flash after.

What VIN do I enter at checkout?

The 17-character VIN of the car you're tuning. It appears on the driver-side dash, door jamb sticker, and registration.
