What is included?
Two power stages: 280 HP and 300 HP. Both run on stock hardware, software only — no downpipe or parts required.
This package is for MOSTUNED Flasher owners: access is added to the Flasher access already on your VIN, and the 280 and 300 stages appear in the app's Flash tab.
No Flasher yet? Do not buy this on its own — the Flasher + 280/300 bundle (€750) is €100 cheaper than buying separately.
Package features (crackle, cold-start delete, Vmax, RPM limiter, OPF/DP, sport cooling) are toggled from the app.
Requirements
Active MOSTUNED Flasher access on your VIN. Turkish-market 1.6 B48B16 (MG1CS003) — 320i (G20), 420i (G22/G26), 520i (G30), X3 sDrive20i (G01). ECU must be unlocked.
FAQ
What if I want 320 too?
Add the 320 HP add-on (€200) later, or buy 280/300 + 320 (€700) upfront.
I do not own the Flasher — can I still buy this?
You can, but you would not be able to write your own file; the bundle (€750) gives you both for €100 less — buy that instead.
Refunds?
No refunds once access is granted; see the terms of use.
