Included features
Alongside the power stage, toggles you control from the app. For track / closed-road use; road legality is the user's responsibility.
Crackle / Pops (adjustable)
Controlled crackle and pops from the exhaust. Rev range, speed and intensity are set from the app — without risking engine health.
Cold Start Delete
Silences the high-idle, noisy warm-up on cold starts. Quiet mornings — fully off or off once warm.
Speed Limiter Off
Removes the factory electronic speed limit (Vmax).
RPM Limiter
Adjusts the rev limit to suit your stage.
OPF / DP Calibration
Compatible calibration for particulate-filter delete or downpipe cars.
Sport Cooling
Earlier, more aggressive cooling for high load and track use.
What is included?
All three stages: 280, 300 and 320 HP. 280 and 300 on stock hardware; 320 requires a downpipe and suitable fuel.
MOSTUNED Flasher included: write the file from your own tuner with the same app.
Upfront: €350 (Flasher) + €500 (280/300) + €200 (320) = €1050, versus €900. We reward buying complete early.

Requirements
Turkish-market 1.6 B48B16 models — 320i (G20), 420i (G22/G26), 520i (G30), X3 sDrive20i (G01). ECU must be unlocked (the app checks for free; if locked, we do the unlock). 320 HP needs a downpipe fitted and suitable fuel.
iPhone + ENET/WiFi-ENET adapter.
FAQ
Do I have to use 320 straight away?
No. Start on 280/300 and move to 320 when your downpipe is ready — all three are in your package.
Why is Full cheaper?
We reward buying complete early: €900 versus €1050 buying one by one — €150 saved.
Refunds?
No refunds once delivered; see the terms of use.
