TUNING
BM3 AUTHORIZED · CUSTOM CALIBRATION
Custom BMW & MINI tuning, calibrated by hand.
We tune the N20/N26, B48, B58, N55, N63, S55, S58, and S63 platforms and the MINI Coopers that share an engine. Every tune is logged, verified, and documented before it ships.

BY STAGE
What each stage means.
STAGE 1
$495 · calibration only
Bolt-on tune for 93oct. Stock or aftermarket downpipe acceptable. The calibration on its own — where most builds start.
STAGE 1 TUNES →STAGE 2
Tune $595 · kit from $1,960
Tune + supporting hardware — catless downpipe, charge cooling, fueling. 93oct or E30 flex. Priced per platform.
STAGE 2 TUNES →STAGE 3
Tune $895 · kit from $15,700
Tune + full hardware path — bigger fueling, often a hybrid or Phantom turbo. E85 territory. Built per car.
STAGE 3 TUNES →Every tune we ship is logged before delivery. Not the demo log — the actual customer-car log on the actual customer-car ECU revision. The number on the dyno is real because the conditions during the calibration session were real. — THE SHOP'S METHODOLOGYREAD THE FULL METHODOLOGY →
