FAQs
Is it safe for daily driving?
Yes — all maps stay within factory safety margins and are proven on thousands of cars worldwide.
Do I need a bench unlock?
No — all N55 E & F series flash directly via OBD (except some very late 2016+ F-series that may need FEMTO — we offer this service).
Can I run full E85?
Yes, custom E85 maps are available through MHD custom tuners.
