02 — The Details
Know It Before You Bolt It.
Still Not Sure It Fits?
Send us your VIN and a builder will confirm fitment before you order.
Check My VINMake Your ZF8 Shift Like It Should Have From The Factory.
BMW's ZF8 8-speed automatic is one of the best gearboxes ever built — but the factory calibration plays it safe: soft shifts, lazy kickdown, slipping clutches under load. A proper transmission tune wakes it up: faster, firmer, more confident shifts and higher torque-holding capacity.
What the tune delivers:
- Faster, harder shifts — crisp, immediate gear changes in Sport & manual mode.
- Higher torque limits — supports your engine mods so the trans stops fighting your power.
- Reduced clutch slip — firmer engagement protects the gearbox under boost.
- Smarter shift logic — holds gears properly, sharper kickdown, less hunting.
Flat fee: $450. Covers BMW ZF8-equipped models. Remote flashing available where supported.
Service only — nothing ships. After checkout you'll get a booking link to confirm your chassis & setup.
