I am considering updating the tune on my 335i N55. From all my lurking on the site, it seems as though most really preferred the Dinan.
But most of those posts were from 5+ years ago. Anybody with updated opinions on quality, impact on engine life, etc?
Thx in advance for any and all input.
BTW: this is part of our project to give my 335i a makeover. Taking suggestions over at: Starting from scratch--E93 mod suggestions?
