BMW Stage 3 Tuning
$1,500.00
DESCRIPTION
Stage 3 is where things get serious. This is a full custom calibration built around upgraded hardware — a larger or hybrid turbo, upgraded fuelling, and the supporting mods needed to make it all work together safely.
Every file is written and refined in-house on our dyno. Stage 3 isn't a load-and-go flash: it's a proper development process, with the car on the dyno over multiple sessions while we build the map around your exact combination of parts.
Hardware requirements
Stage 3 is a hardware-led build. Depending on your platform and power target, it will involve some or all of the following:
- Upgraded or hybrid turbocharger
- Upgraded fuel system — pumps, lines and injectors as required
- Downpipe and full turbo-back exhaust
- Uprated intercooler, heat exchanger and intake
- Supporting engine, cooling and driveline hardware as needed
The exact combination depends on your car, your power target and how you use it. We supply and fit a full range of Stage 3 hardware — get in touch and we'll spec the right package for your build.
Power gains
Stage 3 typically delivers 25% or more outright power over stock, depending on hardware. The turbo, the fuel system and the supporting mods all set the ceiling — talk to us about your target and we'll tell you what's realistic for your platform and budget. Your engine's health and condition will affect these figures.
What's included
- Full custom Stage 3 ECU calibration developed for your exact vehicle and hardware
- Multiple dyno sessions as required to develop and validate the map
- Boost, fuelling and timing calibrated around your specific turbo and fuel system
- Smooth, refined boost control with safety protection logic built in
- OBD ECU remapping
Safety
ANTZ Performance only offers custom ECU tuning, we do not flash tune or use off the shelf tunes. All our tunes are calibrated to your car and we run the car on the dyno as many times as it takes until we are satisfied with no maximum amount of runs. To ensure maximum engine safety at all power levels, ANTZ follows a self-imposed safety system that adheres to OEM protocols for air/fuel ratio and fuelling trims. This keeps your car running as closely as possible to how it was designed to run from the factory, even at boosted power levels — ensuring all our tunes are as safe as possible.
Warranty
We offer a one-month warranty on the tune to allow your new hardware to bed in and settle. After this period a retune fee may apply, as components settle and wear in over time, which can alter the tune's parameters. All tunes are subject to our T&Cs on this website.
Please note: This is a non-physical product (tuning software / service). Gains vary depending on fuel quality, altitude, supporting hardware, and dyno type. Stage 3 is a custom build — please talk to us before purchasing so we can confirm the right package for your car.
